The Capture Theory states that the moon was formed somewhere else but was then captured by Earth’s gravitational pull. The condensation theory states that both the Earth and the Sun condensed together from the original nebula that created the solar system. Unusual Rotation of Uranus Uranus’s rotational axis is nearly horizontal, almost as if the planet has been knocked over. This strange orientation could be from a collision between Uranus and a planet sized body. The magnetic fields are usually in sync with a planets rotation, which means that Uranus’s magnetic fields are also tipped over.
That, in turn, helped them grow even more massive by drawing planetesimals into clumps or rings around the sun. The process of planets building undergoes consumption of most of the planetesimals. Some survived planetesimals form small moons, asteroids, and comets. The leftover Rocky planetesimals that remained between Jupiter and Mars were stirred by Jupiter’s gravitational force. Therefore, these Rocky planetesimals are unable to assemble into a planet.
During this explosion, in less than one second, every element up to and including uranium is synthesized by fusion and dispersed into space. As time passed in the universe, the heavy element content as a whole increased, so new stars were more enriched. Production of planets is an entirely different process. Planets form from the accretion disk surrounding newly formed stars. This material, comprised of dust and rock, collides and sticks together eventually gaining ... ... middle of paper ... ...ls.
Gravity collapsed the matter, forming the sun in the center of the nebula. As the sun came to be, the rest of the material began to clump up and small particles came together and became into bigger and better particles. Solar wind took light elements such as hydrogen and helium, and only left rocky materials such as earth. The solar winds led the rest of the materials to become into gas giants. This also led to asteroids, comets, planets, and moons to be created.
The nebula was thought to be a few light years across and was roughly spherical in shape. The cloud was in a state of balance, it was neither contracting or expanding, until a cataclysmic event, most likely a supernova, created a shock wave through the nebula, resulting in an area of higher mass. Once this area became more massive than the rest of the nebula it begin to collapse with the area of hig... ... middle of paper ... ...planetesimals that once orbited the sun but were, at one point, captured into a planetary orbit by the planet's gravity. Cratering is also a sign of these period, with the collision of planetesimals into larger ones being the explanation. Overall we can get a pretty good insight on how or Solar System was formed, yes there are still certain aspects of it that are hard to make sense of, as well as debates over which theory is correct, such as Core Accretion vs.
It causes heat to flow from the interior toward the surface, where it is released out into space and makes the star shine. Because stars are only so big, they will eventually use up their nuclear fuel and run out of energy. (University of Oregon, Unknown) The first step in making new stars is to compress a cloud in order to strengthen gravity's effect so that the cloud material can contract and break-up into smaller units that eventually collapse to form stars. The clouds in the inter-stellar space are called Inter-stellar Medium, which are mainly made up Rho Ophiuchi of hydrogen and helium. The cloud itself is very cold, somewhere around a hundred degrees Kelvin, which is far below -150ºC.

It isn’t crazy because it is fact that earth isn’t the center. Technology and knowledge has brought us across great voids that we thought weren’t possible to attempt. We flew to the moon in 1969, but now we have the power to fly to Mars.
The footprints of the visiting astronauts will survive for millions of years. Crash and splash Astronomers now believe the Moon is the remains of a giant cosmic traffic accident. In its very early days, the Earth was hit by a runaway planet the size of Mars. White-hot molten rock were splashed into space, and solidified into a ring of rocks around the Earth.

There are five basic theories in the formation of our moon. The first is the "fission theory" which states that the moon was once a part of earth, but separated a long time ago. The second theory is called the "capture theory". This theory is says that the moon formed somewhere else, and was "captured" by earths gravitational pull. The third theory is called the "condensation theory" this theory states that the moon and earth were condemned together from the original nebula that formed our solar system.
