Some Interesting Facts about Planets
Mercury, which is the closest to the Sun, is the second densest planet in the solar system and has no natural satellites.
Venus: It is probably the first planet identified, as it is the brightest object in the sky with the exception of Sun and moon. Even though Venus occupies the second position it is hotter than Mercury because of its very dense atmosphere. Like Mercury, it too doesn’t have a natural satellite.
Earth: It is the only planet in the solar system which sustains life. It is the densest planet among the eight members of the solar system and has one natural satellite; the moon.
Mars: Circled by two small natural satellites, this red planet follows the sun in a greatly elliptical orbit. In addition to that it is the site of Olympus Mons, the largest mountain in the solar system.
Jupiter: It is both the biggest and the fastest planet and has the most moons in the solar system.
Saturn: Often identified by its rings, this planet is the second both in size and in number of moons in the solar system. Even though all Jovian planets have rings, Saturn’s rings are the most conspicuous.
Both Uranus and Neptune are blue in colour and have a number of moons.
