READING AND COMPREHENSION
The Solar System
The solar system is the Sun and the objects that travel around it. The Earth is part of the solar system because it also travels
around the sun.
The Sun is a star similar to the other stars in the sky but it is much closer to the Earth. The Sun is mostly a big ball of gases
composed mainly of hydrogen and helium.
There are seven other planets that travel around the sun, too. These planets, in order, include Mercury, Venus, Mars, Jupiter,
Saturn, Uranus, and Neptune. Earth is located between Venus and Mars. The path the planets use when traveling around the
sun is oval-shaped and is called its orbit. Each of the planets in the solar system take a different amount of time to orbit or travel
around the Sun.
The planet Earth takes 365 days or one year to orbit the Sun. The other planets take more or less time to orbit the Sun. It takes
Mercury less than two months or 88 days to travel around the Sun. It is the shortest time compared to the other planets. The
planet taking the longest time to go around the Sun is Neptune. It takes Neptune almost 165 years to travel around the Sun.
The planets of the solar system are also a variety of sizes and are made up of different substances. The largest planet in the
solar system is Jupiter. Over 1,000 Earths could fill the size of Jupiter. The smallest planet is Mercury, which is also the closest
planet to the Sun. Earth and Venus are similar in size to each other.
The four inner planets, Mercury, Venus, Earth, and Mars are made of rock containing many different minerals. The four outer
planets, Jupiter, Saturn, Uranus, and Neptune are mostly made up of different gases. Jupiter is mainly helium, hydrogen, and
water. The four outer planets also have rings that encircle them with Saturn having the most rings.
