WHAT IS A PLANET? Planet, any major celestial body that orbits a star and does not emit visible light of its own but instead shines by reflected light.
NAMES OF PLANET
Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto
MERCURY Mercury orbits closer to the Sun than any other planet, making it dry, hot, and virtually airless.
VENUS Venus has a carbon dioxide atmosphere 90 times thicker than that of Earth, causing an efficient greenhouse effect by which the Venusian atmosphere is heated.
EARTH An oxygen-rich and protective atmosphere, moderate .temperatures, abundant water, and a varied chemical composition enable Earth to support life, the only planet known to harbor life.
MARS Planet’s atmosphere consists primarily of carbon dioxide, with small amounts of nitrogen, oxygen, water vapor, and other gases.
JUPITER Jupiter is the largest of the planets, with a volume more than 1,300 times greater than that of Earth. Jupiter’s colorful bands are caused by strong atmospheric currents and accentuated by a dense cloud cover.
SATURN Saturn, distinguished by its rings, is the second largest planet in the solar system. This processed Hubble Space Telescope image shows the planet’s cloud bands, storms, and rings as they would appear to the human eye ..
URANUS Uranus’s blue-green color comes from the methane gas present in its cold, clear atmosphere. The dark shadings at the right edge of the sphere correspond to the day-night boundary on the planet
Neptune The large, dark oval surrounded by white clouds near the planet’s equator is the Great Dark Spot, a storm similar to Jupiter’s Great Red Spot
PLUTO Pluto is farther from the Sun than the other planets in the solar system, although it occasionally moves in closer than Neptune due to an irregular orbit. The small, rocky, and cold planet takes 247.7 years to revolve around the Sun.
