Ø The
Sun is over 300000 times larger than earth. More Sun facts.
Ø Halley’s
Comet was last seen in the inner Solar System in 1986, it will be
visible again from Earth sometime in 2061 (get your camera ready). More comet facts.
Ø Venus is
the hottest planet in our solar system with a surface temperature of over 450
degrees celcius.
Ø Many
scientists believe that an asteroid impact caused the extinction of the
dinosaurs around 65 million years ago. More asteroid
facts.
Ø The
Solar System formed around 4.6 billion years ago. More Solar
System facts.
Ø The
Moon appears to have more craters and scars than Earth because it has a lot
less natural activity going on, the Earth is constantly reforming its surface
through earthquakes, erosion, rain, wind and plants growing on the surface,
while the moon has very little weather to alter its appearance. More Moon facts.
