The planets are Mercury, Venus, Earth, Mars (the inner planets), Jupiter, Saturn, Uranus, and Neptune. The definition of a dwarf planet is a planetary-mass object that is object that is neither
a planet nor a satellite (the wikipedia definition). The dwarf planets are Pluto, Eris, Haumea (egg planet), and Makemake. In the farthest reaches of the Solar System, there is the Kuiper Belt, which is a belt of asteroids just past Pluto and Eris. The comet is Halley's Comet. A comet is big ball of ice and dust that orbits a star. The sun is so big it takes up 99.98% of the mass in the solar system. My favorite planet is Uranus because it's sideways. Instead of spinning on a top and bottom axis, it spins on a horizontal axis.
What's your favorite planet?
