    •The Sun produces so much energy, that every second the core releases the equivalent of 100 billion nuclear bombs.

    •Galileo Galilei is often incorrectly credited with the invention of the telescope. Instead, historians now believe the Dutch eyeglass maker Johannes Lippershey as its creator. Galileo was, however, probably the first to use the device to study the heavens.

    •Black Holes are so dense, and produce such intense gravity, that even light can not escape. Theoretical physicists predict that there are situations under which light can escape (which is called Hawking radiation).

    •Light from distant stars and galaxies takes so long to reach us, that we are actually seeing objects as they appeared hundreds, thousands or even millions of years ago. So, as we look up at the sky, we are really looking back in time.

    •The Crab Nebula was produced by a supernova explosion in 1054 A.D. The Chinese and Arab astronomers at the time noted that the explosion was so bright, that it was visible during the day, and lit up the night sky for months.

    •Shooting stars are usually just tiny dust particles falling through our atmosphere. Comets sometimes pass through Earth’s orbit, leaving trails of dust behind. Then as Earth plows through the dust in its path, the particles heat up, creating the streaks in the night sky.

    •Even though Mercury is the closest planet to the Sun, temperatures can reach -280 degrees F. Why? Since Mercury has almost no atmosphere, there is nothing to trap heat near the surface. So, the dark side of Mercury (the side facing away from the Sun) is very cold.

    •Venus is considerably hotter than Mercury, even though it is further away from the Sun. The thickness of Venus’ atmosphere traps heat near the surface of the planet.

    •Scientists believe that we can only see about 5% of the matter in the Universe. The rest is made up of invisible matter (called Dark Matter) and a mysterious form of energy known as Dark Energy.


    •Neutron stars are so dense, that a soup can full of neutron star material would have more mass than the Moon.

    1. The Sun is so big that 106 Earths could fit across its diameter and 1,300,000 Earths could fit inside of it.

    2. Jupiter is actually pretty big, but still not even close to being as big as the Sun. It's so big 1,300 Earth's could fit inside of it.

    3. The Sun is so big that Jupiter is just as big as it's core.

    4. The Sun accounts for 99.8% of the Solar System's mass. Now that's big.

    5. There is another planet around a different star, known as extrasolar planets, that is 5 times bigger than Jupiter, and it's name is 2M1207b.

    6. There is a star, called Betelgeuse, that is 450,000,000 miles in diameter, and the Sun is just a dot compared to it. Now that's really big.

    7. Jupiter has 63 moons! While Saturn has 60 and the planet with the 3rd most moons is Uranus with only 27 moons, but that's still a lot compared to Earth with only 1.

    8. Did you know that the Sun actually rotates on an axis, well it does.It takes the Sun 25 days to turn on its axis.

    9. The biggest moon in the Solar System is, of course, around Jupiter. It is called Ganymede and it is 3,280 miles in diameter. And of course the second biggest moon is around the second biggest planet, Saturn. That moon is Titan which is 3,200 miles in diameter.

    10. Also, did you know that our Moon is the 4th biggest in our Solar System.

    Fun Facts About The Sun

    •The Sun is 4.5 billion years old and produces 383 billion trillion kilowatts of energy.
    •Sunlight takes 8 minutes to reach the Earth and is responsible for the ocean currents and weather patterns on our planet.
    •The Earth orbits the Sun in an elliptical uneven orbit and the distance between them varies depending on where the Earth lies in that orbit.
    •The solar winds produced by the Sun extends to about 50AU, where AU is the distance from the Earth to the Sun.
    •The lightning in the sky is nearly 3 times hotter than the Sun.
