Science Studying Homework

NOTES ON PLANETS:

• The sun appears 2 and a half times larger in Mercury's sky compared to the Earth's.
• Venus is known as Earths' twin sister because of its similar size and proximity to each other.
• The Earth is estimated to be 4.5 billion years old. It travels through space at 660,000 miles per hour
• Mars is red because it is rusty. There is a lot of iron in the soil, and the air on Mars has made it turn red-just like rusty iron on Earth.
• If you weigh 100 pounds on Earth, you would weigh 264 pounds on Jupiter.
• A 100 pound object on Earth would weight 116 pounds on Saturn.
• Because of the strange way it spins, nights on some parts of Uranus can last for more than 40 years.
• Neptune is so far away that it took the space probe Voyager 2, 12 years to reach it.
• Pluto is smaller than the Earth's moon.
