Amazing Astronomy Facts

  1. When Galileo viewed
    Saturn for the first time through a telescope, he described the
    Huygens suggested the crazy theory that they might be an
    enormous set of rings around the planet.

  2. If you could put Saturn in an enormous bathtub, it would float. The planet is
    less dense than water.

  3. A teaspoon-full of Neutron star would weigh about 112 million tonnes.

  4. Jupiter is heavier
    than all the other planets put together.

  5. Even on the clearest night, the human eye can only see about 3,000 stars.
    There are an estimated 100,000,000,000 in our galaxy alone!

  6. The tallest mountain in the solar system is Olympus Mons, on Mars at a
    height of about 15 miles, three times the height of Mount
    . It covers an area about half the size of

    star would be 10 miles away.

  8. Half-a-billionth of the energy released by the sun reaches the Earth

  9. Temperatures on Venus are hot enough to melt lead.

  10. If you could travel at the speed of light (186,000 miles per second) it would take
    100,000 years to cross our galaxy!

  11. Only one side of the moon ever faces Earth. The moons period of rotation is
    exactly the same as it's period of orbit.

  12. Betelgeuse, the bright star on Orion's top-left shoulder, is so big that if it

  13. If you stand on the equator, you are spinning at about 1,000 mph in as the Earth

  17. If a piece of the sun the size of a pinhead were to be placed on Earth, you could
    not safely stand within 90 miles of it!

  18. Its estimated that the number of stars in the universe is greater than the number

  19. Every year the sun evaporates 100,000 cubic miles of water from Earth (that weighs
    400 trillion tonnes!)

  20. Jupiter acts as a huge vacuum cleaner, attracting and absorbing comets and
    meteors. Some estimates say that without Jupiters gravitational
    influence the number of massive projectiles hitting Earth would
    be 10,000 times greater.

  21. Astronomers believe that space is not a complete vacuum- there are three atoms per
    cubic metre.

  22. Saturn is not the only planet with rings- Neptune has it's
    own ring system.
