    to 18. Neptune: Neptune was discovered through a discrepancy in Uranus’s orbit. Uranus’s orbit was not moving how astronomers predicted it would. They could not find an elliptical orbit that fit Uranus’s trajectory. They therefore assumed that there had to be another planet that’s gravitational pull was effecting Uranus. Johann Galle was the first to find Neptune in 1846, even though many before him had mathematically predicted where this new planet would be. The planet was named Neptune and two

    talk! “Hi, my name is Reneesme and I’m from Neptune I came to Earth to make friends.” My eyes were wide open, I couldn’t believe it.

    tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earth’s neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earth’s neighbours. They all have the same stars in the sky and orbit the same sun. Scientists believe the solar system began about 5 billion years ago, perhaps when a nearby star exploded and caused a large cloud of dust and

Jovian means "Jupiter- like" in which the rest of the jovian planets do coincide with the name. Uranus Neptune and Saturn, all carry the same traits as Jupiter. The jovian planets are large gas giants that contain mainly a thick atmosphere of Hydrogen and helium. These planets do not have solid surfaces, rather they just get denser with

    was a very important invention in history. Special Event- Neptune Discovered (September 23, 1846)- Neptune is the eight planet in our solar system and sometimes the ninth. As an effect of Pluto’s orbit, Pluto sometimes crosses in front of Neptune for a couple years. In 1613, Galileo saw Neptune and predicted it was just a star. In 1845, Urbain Jean Joseph Le Verrier and John Couch Adams mathematically predicted the location of Neptune. Then, Le Verrier asked Johann Gottfried Galle and Heinrich
