Dark, mysterious, and rarely traveled, outer space piques the curiosity of people young and old. If your daydreams take you on intergalactic adventures, check out NASA's facts about the planets:
1) The average temperature on Venus is about 900 degrees Fahrenheit. Some areas on this planet are hot enough to melt lead. Likely due to Venus's extreme temperatures, no evidence of life has ever been found on the planet.
2) Mercury is the fastest planet in the solar system: A year on Mercury is equal to 88 days on Earth! Mercury is also the smallest planet in our solar system; it's a little smaller than Earth's moon.
3) Mars is cold and desert-like. It has seasons; however, the conditions of its atmosphere does not allow its surface to retain liquid water for long.
4) Enveloped by rings of ice and rock, Saturn is composed mainly of hydrogen and helium. The planet has three orbiting moons.
5) The winds on Neptune can reach up to 1,600 miles per hour, making Neptune the windiest planet in the solar system.
6) Jupiter has plenty of moons with different climates. One of the four largest moons is covered in ice, while another one of Jupiter's moons is the most volcanically active in the solar system.
