Uranus was the first planet to be discovered in 1781.
False. A moon, by definition, orbits a planet.
The Van Allen Belts are the radiation belts surrounding the Earth. They were discovered in 1958 by NASA's astronomers and scientists.
Jupiter is the fifth planet from the Sun and the largest in the Solar System. Jupiter can be seen without a telescope and has been known since ancient times. Galileo was one of the first astronomers to classify Jupiter as a planet.
Planet X is a hypothetical planet once thought to exist out beyond Neptune. Astronomers discovered a discrepancy in Uranus' orbit that they thought indicated another planet beyond Neptune whose mass was affecting it. When Neptune's mass was determined using data gathered by Voyager 2, Astronomers discovered that the discrepancy was entirely due to Neptune's orbit. Since then, other trans-Neptunian objects have been discovered, but none large enough to be considered a planet.

The earth as planet was discovered by some of the ancient astronomers. Nicolaus Copernicus and Ptolemy are credited with provision of the initial information of the earth as a planet in relation to the solar system.
Astronomers have newly discovered a planet , Gliese 581g, within the "Goldilocks" zone - see related link to the news article .
Unfortunately, no extraterrestrial life has been discovered to date, but astronomers are always on a close lookout!
Astronomers are constantly finding new planets orbiting stars other than our sun. In 2005 astronomers discovered a new object, later named Eris, which almost become the tenth planet. The discussion of this object resulted in a new definition of a planet which excluded Eris.

Neptune was predicted by astronomers be observing the effects of its gravity. Neptune was discovered in 1846 by Johann Gottfried Galle.
that would ruin the very definition of a moon. a moon is an object that orbits a planet, so it's impossible.
