Our Sun • 330,000X greater mass than Earth. • If the Sun were the size of a soccer ball, the Earth would be the size of a BB. • It’s HOT! And it’s HUGE! The Terrestrial Planets (Made mostly of rock and metal) • • • • Mercury Venus Earth Mars Mercury • Closest planet to the Sun. • Orbits the Sun in only 88 days! Venus • The brightest object in the sky next to the Sun and Moon. • Orbits the Sun in 225 days. Earth • Our home. • The densest planet. • Orbits the Sun in 365 days. • Has a large supply of unfrozen water. Earth’s Moon • The only natural satellite of Earth. • Second brightest object in the sky, after the Sun. • The Moon’s gravity is the main cause of our tides. Mars • Orbits the Sun in 687 days. • Sometimes referred to as the “Red Planet”. • Has the largest mountain in the solar system - 78,000 feet. Asteroid Belt • Most of them are located in a “belt” between Mars and Jupiter. • The total mass of all known asteroids is less than that of the Moon. Gas Giant Planets • • • • Jupiter Saturn Uranus Neptune Jupiter • Largest planet in our solar system. • More than twice as big as all of the other planets combined. • Takes 4,333 days to orbit the Sun. • Made of 90% hydrogen and 10% helium. Saturn • Takes 10,760 days to orbit the Sun. • Sixth planet from the Sun. • 2nd largest planet. • Least dense of the planets. • It’s made of gases hydrogen and helium. Uranus • Takes 30,685 days to orbit the Sun. • Spins sideways. • Made of rock, ice, hydrogen, and helium. Neptune • Takes 60,190 days to orbit the Sun. • 4th largest planet. • Made of ice, rock, hydrogen, and helium. Pluto (Dwarf Planet) • Smaller than 7 of the solar system’s moons. • Sometimes crosses the orbit of Neptune, making Neptune the most distant planet from the Sun for a few years. • Takes 90,550 days to orbit the Sun.
