4. PLANETS A planet is a large, round heavenly body that orbits a star and shines with light reflected from the star. We know of eight planets that orbit the sun in our solar system. Since 1992, astronomers have also discovered many planets orbiting other stars. World book

6. MERCURY Mer|cu|ry «MUR kyuhr ee», noun. The smallest planet in the solar system, after Pluto, and the one nearest to the sun. Its orbit about the sun takes 88 days to complete, at a mean distance of almost 36,000,000 miles. Mercury goes around the sun about four times while the earth is going around once.

9. MARS Mars is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance as seen from Earth.

11. What is this planet called?

12. Jupiter Jupiter is the largest planet in the solar system. Its diameter is 88,846 miles (142,984 kilometers), more than 11 times that of Earth, and about one-tenth that of the sun. It would take more than 1,000 Earths to fill up the volume of the giant planet. When viewed from Earth, Jupiter appears brighter than most stars. It is usually the second brightest planet—after Venus. Jupiter is the largest planet in the solar system.

13. SATURNS

14. SATURN Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Along with the planets Jupiter, Uranus and Neptune it is classified as a gas giant (also known as a Jovian planet, after the planet Jupiter).

15. URANUS Uranus is the seventh planet from the Sun and the third- largest planet in the solar system. Uranus was the first planet discovered in modern times. Though it is visible to the naked eye like the five classical planets, it was never recognized as a planet by ancient observers due to its dimness. Sir William Herschel announced its discovery on March 13, 1781, expanding the known boundaries of the solar system for the first time in modern history. This was also the first discovery of a planet made using a telescope.

16. NEPTUNE Latin, related to nebula cloud, mist Latin, related to nebula cloud, mist In Neptune's outermost ring, 39,000 miles (63,000 kilometers) from the planet, material mysteriously clumps into three bright, dense arcs. NASA

17. PLUTO Is Pluto a planet? Prior to August, 2006, Pluto was considered a planet. However…

18. Pluto – YOU’RE OUT! According to the new definition, a full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit. According to the new definition, a full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit. Pluto has been demoted because it does not dominate its neighborhood. Charon, its large "moon," is only about half the size of Pluto, while all the true planets are far larger than their moons. Pluto has been demoted because it does not dominate its neighborhood. Charon, its large "moon," is only about half the size of Pluto, while all the true planets are far larger than their moons. In addition, bodies that dominate their neighborhoods, "sweep up" asteroids, comets, and other debris, clearing a path along their orbits. By contrast, Pluto's orbit is somewhat untidy.
