Friday, August 9th is the first of three consecutive nights you will be able to see Saturn, Jupiter and the Moon all together nearly in a straight line according to Earthsky.org.

They will be visible throughout most of the night and if you are up before dawn you can see Mercury for just a moment prior to the sunrise. Bet you didn't know these fun planet facts.

  • Jupiter's diameter 11 times bigger than Earth -- meaning you'd have to put 11 Earths side-by-side to match Jupiter's diameter.
  • Its surface gravity is nearly three times that of Earth.
  • To escape Jupiter's gravity, you'd have to travel 134,664 mph. Earth's escape velocity is 25,031 mph.
  • Jupiter's Great Red Spot is a giant storm that is larger than Earth and has been going on for hundreds of years.
  • One Jupiter year takes nearly 12 years on Earth.
  • Jupiter has 75 moons.
  • Saturn's diameter is 9.1 times bigger than Earth's.
  • Its surface gravity is only slightly more than Earth's (34.3 feet per second squared compared to 32.041 feet per second squared).
  • Like Jupiter, it's mainly a giant ball of gas made up of hydrogen and helium.
  • One Saturn day lasts 10.7 Earth hours. Its year lasts 29 Earth years.
  • Saturn has 53 moons.

So bring out a lawn chair and check out this rare sighting.
