Transcript of Halley's Comet

Halley's Comet
By: Allison

This comet is named after Edmond Halley, after he saw it 2 times.
This is Him
First Things First
Halleys comet is arguably the most famous
comet. It comes by every 75-76 years.
Who it is Named After
The difference of a comet and an asteroid is that asteroids are big rocks. Comets actually have tails!
An asteroid is different than a comet because comet is frozen and asteroids are just rocks. How comets get their tail is because some of the ice melts and vaporizes to form a tail. And the color, well I guess it is from the vapor too.
The last time it was seen was in 1986, and will return in 2061. Possibly when you are still alive.
