Comets

Comets are made up of gas dust and ice .

They are in the Oort cloud and the Asteroid belt.

You rarely see a comet in your  life.

When a comet gets close to the sun the ice

start melting. Making a tail or coma around

the ball or nucleus . Sometimes comets smash

into planets or get burned by the sun. One well

know comet is Halley's comet which last came in

2003 and will come again  around 2061. I will be able

to see it ! Halley's comet is named after Edmund Halley

who found the orbit of the comet.  Comets orbit the sun.

They Come close to  it ( that is when we see them )

Then travel far far away like to the Oort cloud .
