Mercury
Mercury is the closest planet to the sun, along with venus, earth, mars. It is mostly made of rock. In 1974, Mariner 10 took pictures of mercury and scientist thought it looked like earth’s moon. It itself has no moons. It is named after the Greco- Roman Messenger of the gods, because it moves faster than all the other planets. Mercury has a crater known as Caloris Basin, Scientists believe the crater was made when an asteroid hit the planet. The crater is about 810 miles (1,300 km) You can see mercury at sunset or sunrise low in the horizon. Mercury is the only planet that has no atmosphere, any gases will escape into space. Without an atmosphere, the day is hot and dry, the night is freezing cold. It is made out of rock, its iron

Earth is our planet, the only planet known to support life. There are 7 continents on the earth. When the universe first started, and dinosaurs were alive, all the continents were connected into one continent called pangaea. Later on in life, the plates moved the earth, so some substances were spread all around, as well as the skeletons of the dinosaurs. Earth is made out of a molten iron core, with rocky plates that move the surface of the earth. About 70% of the earth is covered in water, and only 2% is fresh (rest is contaminated, salted) and only 1% is actually water, the rest is glaciers. the earth’s atmosphere is composed of 78% nitrogen, 21% oxygen, and 1% of other gases which include water vapour and carbon dioxide. One day has 23 hrs, and 56 min. Every four years, there is one day added to February (29th) which all the minutes of every day add up into one full day. It takes 365. 3 days to orbit around the sun. the earth spins on its axis as it orbits around the sun. Earth is a little slanted on its axis with our moon orbiting around us. Earth’s gravity is 9.807 m/s2. (“Popular Science …show more content…
In 1979, the Voyager 1, the third spacecraft to fly by jupiter; proved that jupiter has one small ring around it. There are never ending storms on jupiter. The reason storms never is because there is no land and no surface. The Geosphere usually will stop a storm or hurricane from continuing and will just fade away. However, this is not the case for jupiter as it has no surface. Jupiters two main moons is Io and Europa. Io has many volcanoes that continuously erupt hot lava. Scientists believe that Europa, due to its ocean under its icy surface may have eternal life there. Jupiter’s atmosphere is mostly composed of hydrogen gas. Jupiter is made of huge storms that go on for thousands of years. The winds blow faster than 400 miles/ hr. Jupiter does not have a solid surface. It’s atmosphere of gas and ice push down onto the center. The pressure makes jupiter hot and thick. There may be a rocky core in the middle. Jupiter spins very quickly on its axis. It takes 9hrs and 55 for a day to end. It orbits extremely slowly around the sun, it takes about 12 earth years to orbit once. It has a total of 63 moons. More than 1,300 earths could fit into jupiter.
Jovian Planets are the next four planets in our solar system and are also known as “gas giants”. These four planets consist of Jupiter, Saturn, Uranus, and Neptune. Jovian planets are different from Terrestrial planets in that they are farther from the sun, which makes them cooler, mostly gaseous in composition, have low density and fast rotation. Some of the planets also have rings

Supernovas are accountable for the birth of new galaxies and stars, including the Milky Way and its planets. Jupiter is the center of many theories. One speculation considers Jupiter’s core to be solid diamond, or highly compressed carbon. Due to the abnormal mass of the planet, Jupiter has strange weather conditions that lead to large storms, including its Great Red Spot, an anti-cyclonic storm.
Introduction From the Earth to the Moon, the Eagle has landed, the Apollo XI spacecraft has made it to the moon with fierce determination of Neil Armstrong, Buzz Aldrin, Michael Collins with only 30 seconds of fuel remaining! Don’t you ever wanted to know how these famous astronauts got up there? Well, it’s your luck day, I will be talking everything about Apollo XI from astronauts to overview of the mission. The Apollo XI is the most known rocket than any other, it is how the first astronaut went up to the Moon for the United States. It is also the rocket that beat Russia before they got to the Moon in the Space Race.
Pluto was discovered on February 18, 1930. Its greater distance means its orbital period of 248 years is the longest of all planets. The plane of Pluto's orbit is also tilted the most compared to the rest, taking it further north and south of the Earth's orbital plane than the other planets. Pluto's only know satellite, Charon, is the largest satellite compared to the size of its mother planet. The Earth's moon held that title until Charon was discovered in 1978. Charon's large mass relative to Pluto means that the center of their common orbit about each other lies outside Pluto's surface, another unique characteristic of this Planet. The four inner planets Mercury, Venus, Earth and Mars are known as terrestrial planets for their smaller size,
The ancient cultures like the Romans were the first to discover and name the planet Saturn but Galileo was the first to discover the rings in 1610 using his newly invented telescope. Bostiling a elegant ring system Saturn the sixth planet away from our sun at a distance of 1.4 billion kilometers. Saturn is second largest planet in the solar system and here on Earth is visible at night with the naked eye. Saturn has an overall hazy yellow-brown appearance from earth view but with a telescope people can see layers of cloud with little red, brown, and white spots.
Neptune is one of the eight planets in our solar system. It was named after the Roman god of the sea. It was discovered on September 23rd 1847 by Heinrich D'Arrest and Johann Galle. No one before this time knew that Neptune existed, because Neptune is invisible to the naked eye. Neptune is known as an ice giant, but is the smaller than the other ice giant, Uranus. Neptune is the farthest planet from the sun at about 2.8 billion miles away, therefore making it the coldest planet. Neptune is the most dense out of all of the other planets in our solar system. It takes about one hundred and sixty five years for neptune to orbit the sun. Since Neptune does not have a solid surface, the lengths of days are different in different parts of Neptune.
Jupiter, the largest planet in our solar system, has yet to be discovered as in depth as Juno will. NASA New Frontiers recently established the Juno Mission to observe Jupiter (Ionescu 1). The spacecraft is currently on route to Jupiter and it is set to arrive in 2016. Juno will orbit Jupiter thirty-three times total before shutting down (Ionescu 1). Juno will observe Jupiter with deeper observation than can be seen by a telescope. The Juno Spacecraft is a project made to discover Jupiter’s high winds, a possible water source, and the planetary structure.
They are the four largest planets in our solar system if not by mass, then by diameter with Jupiter having the status of being the giant among the giants by acquiring greater than twice the mass of all the other planets in the solar system combined. Just using Earth as a comparison, Jupiter's mass is more than three hundred times larger.
General Description: Earth may be the most unique of all planets because of the life forms we know exist here and the way they utilize the Suns energy. The Earth is composed of a great amount of water, mostly in the form of oceans, which make up most of its surface. It also contains various gases, of which make it possible for us humans to exist and is a system that exists between plants and animals here.
Jupiter’s chemical composition makes it to be the largest planet. Ceres is the largest body in the
It has two small moons which will eventually submit to Mars’s gravity and become rings of dust particles. Jupiter is the largest and most massive planet at 778 million kilometers from the sun with temperatures between -150 and -93 degrees celsius. It is composed largely of hydrogen and helium. It harbors an enormous red hurricane three times as large as earth. 67 moons orbit Jupiter. Saturn, with 62 moons, is the second largest planet, albeit the least dense. It is 1.429 billion kilometers from the sun with a temperature range of -133 to -143. 2.877 billion kilometers from the sun lies Uranus which has temperatures between -200 and -195. It is the smallest gas giant. Its axis of rotation is uniquely vertical. It has 27 moons. With temperatures that descend from -197 to -203,the most distant planet orbits the sun from a distance of 4.5 billion kilometers.One year on Neptune is 164 years on Earth. The most intense storm speed ever recorded occurred on
Mercury is the first planet closest to the Sun. It is the smallest planet in the solar system. Mercury rotates three times in two of its years. One of Mercury's days is equal to 176 Earth days because its rotation is very slow. What is weird is that its day is longer than its year. Mercury’s year is about 88 earth days the shortest in the solar system. It has the shortest year because it is closest to the Sun.
¬¬¬¬¬¬¬¬¬¬¬¬The Earth is a large and mysterious planet that we are just beginning to understand. There are many cycles and forces that go hand in hand in creating different environments on Earth. In this essay we will go over the five major cycles, the Atmosphere, Sun, Water/Ocean, Wind, and Earth cycles. We will also go over how the cycles interact and work together to form one of the most bio diverse planets in our galaxy.
