Thanks to imagery from various space probes, we are just beginning, in the last 20 years, to really get good close looks at cometary nuclei. The biggest we are aware of is about 14 kilometers (10 miles) wide, most are half to two-thirds that size. How "big" a comet appears when it swings around the sun has more to do with how close it passes than it's size.

What is a meteor strike?

A meteor strike occurs when a meteoroid, a small rocky or metallic body from space, enters the Earth's atmosphere and survives its passage to impact the ground. This event can create craters, produce shock waves, and cause damage depending on the size and speed of the meteoroid. While most meteoroids burn up in the atmosphere, larger ones can lead to significant geological and ecological effects upon impact. Meteor strikes are relatively rare but have played a crucial role in Earth's history, including mass extinction events.


What is it called when a meteor produces enough light to cast a shadow on the earth?

A meteor does not produce light, a shadow on the Earth is caused when the meteor blocks the Sun's rays. The meteor does this when it is placed in between the Sun and the Earth, this is called an eclipse.


Will the world end if a meteor hits the earth?

It depends on the size of the meteor. A large enough meteor could cause widespread destruction and potentially lead to the end of human civilization, but it is unlikely to cause the end of the world as a whole. NASA and other organizations actively monitor for potentially hazardous asteroids and comets to mitigate this risk.
