Planets- A planet is a large, round object that orbits around the Sun. Our Earth is one of these planets. It takes about a year for Earth to go all the way around the Sun. There are other planets that do the same thing., There are eight planets in our Solar System, listed in order of their distance from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune., The four planets closest to the Sun- Mercury, Venus, Earth, and Mars—are smaller and have solid surfaces covered with rocks. , . Venus is often seen shining brightly in the morning and evening, which is why people sometimes call it the Morning Star or the Evening Star, even though it is not a star.  , . Mars is known as the Red Planet because its soil is reddish in color. , Earth -A large part of Earth's surface is covered with water, which makes it look blue from space. Because of this, Earth is also called the Blue Planet. , The four planets farthest from the Sun—Jupiter, Saturn, Uranus, and Neptune—are much larger than Earth and are mostly made of gas. These giant gas planets have big, flat rings around them made of dust and rock. , Planets get most of their energy from the Sun. Generally, the farther a planet is from the Sun, the colder it is. However, a planet's atmosphere can trap heat and make it warmer. For example, Venus is hotter than Mercury even though it is farther from the Sun., Among the planets, Venus is the easiest to see because it is very bright. After the Sun and the Moon, Venus is the third brightest object in the sky. Mercury, Mars, Jupiter, and Saturn can also be seen without a telescope, but they look like small, shining dots, similar to stars., Pluto Pluto is an object that lies beyond Neptune and also revolves around the Sun. It is smaller than Earth's Moon. When Pluto was first discovered, it was considered a planet in our Solar System. , However, as more small objects similar to Pluto were found, the International Astronomical Union (IAU) redefined what qualifies as a planet in 2006. According to this new definition, Pluto and other similar objects are now classified as dwarf planets..
