Venus• The planet is named after the Roman goddessof love and beauty.• The atmospheric pressure on the surface ofVenus is that 90 times the pressure on Earth.• Venus is classified as a terrestrial planet and issometimes called Earths "sister planet" owingto their similar size, gravity, and bulkcomposition
Earth• Earth formed approximately 4.54 billion yearsago, and life appeared on its surface within itsfirst billion years.• The Earth has only one satellite, the Moon.The Moon is the second brightest object in thesky.• The planet is home to millions of species oflife, including humans.
Mars• Mars is the fourth planet from the Sun andthe second smallest planet in the SolarSystem.• Named after the Roman god of war, it is oftendescribed as the "Red Planet", as the ironoxide prevalent on its surface gives it a reddishappearance.• The orbital speed of Mars is 24.2 km persecond
Jupiter• Jupiter, the largest planet in our solar system,is 318 times larger than Earth.• Jupiter is primarily composed of hydrogenwith a quarter of its mass being helium,although helium only comprises about a tenthof the number of molecules.• Jupiters mass is 2.5 times that of all the otherplanets in the Solar System combined
Saturn• Saturn is the sixth planet from the Sun andthe second largest.• Saturn has a prominent ring system thatconsists of nine continuous main rings andthree discontinuous arcs, composed mostly ofice particles with a smaller amount of rockydebris and dust.• Saturn is termed a gas giant, but it is notentirely gaseous.
Uranus• Uranus is the third largest planet in the SolarSystem.• Uranus is similar in composition to Neptune,and both are of different chemicalcomposition than the larger gas giants Jupiterand Saturn.
Neptune• Neptune is the fourth largest planet in theSolar System.• Neptune was the first planet found bymathematical prediction rather than byempirical observation.
