• Comets were discovered by danish astronomer tycho brahe in 1577.
• Haleys comet was named after comond halley.• Isaac newton showed that a comets movements are
much like the same laws that control the planets orbits.

• Comets are usually about 9.2 million miles from earth.
• Sometimes comets get in the way of another comet and they will collide.

• Comets have an icy body. Therefore they are super cold.
• The atmosphere around a comet is a gas cloud.

• There are many different
kinds of comets.
This is a list of them:
Main belt comets, centaurs,
krentz sungrazers,
short period comets,
and great comets.

• The physical characteristics of comets are that they have an icy body that releases gas or dust.

• No life on comets could not exist because comets are made of ice, dust, and little pieces of rocks; therefore it is impossible to go to a comet.

• Asteroids were made when something hits a planet or moon and a piece of rock chips off.
• Asteroids are known to be grouped together in an asteroid belt.

• The main asteroid belt is about 5 km from the earth.

• Asteroids are made of rocky chunks of matter in orbit around the sun.

• Asteroids are varied in their composition.
• Most are made of rock, but some are composed of metals and other materials.

• Asteroids range in size and are just rocks.

• Life could not exist on an asteroid because it is just a giant rock.

• Every asteroid is different because of the different sizes,orbits, and compositions; But the average asteroid in the asteroid belt is about -150C.
• Around an asteroid is usually rocks, cold ice, dust, and other minerals.

• They have only found 7 meteoroids that have hit earth in history.
• All of the 7 that hit earth were large impact.

• Most meteoroids move close to the earth, however, only few of them hit earth. The rest of them just pass by.

• Meteoroids are 3.5x more dense then an earth rock
• Their size is at least the size of speck of dust but smaller then an asteroid.
• Meteoroids are made of a small piece of dust, rock, ice, or metal.

• Meteoroids are mainly iron.
• Meteoroids temperature depends on weather in sunlight or moonlight.
• Move at light speed.

• No life could not exist because a meteoroid is just a fast moving space rock and will get to cold and to hot.
