Comets and Deep Impact Mission

by: Meghana Kalavagunta- 5th period

First of all...what is a comet?

-Comets can be a few miles long.

- They live in the Kuiper belt.

-They are large icy structures until they come closer to the sun, where they start to melt.

-When they come close to the sun, comets melt to form a ‘tail’ called the Coma, giving the comet it's shape.

-No matter what, the Coma will face away from the Sun.

Tempel 1

-Tempel 1 is a comet that lives in the Kuiper Belt.

-Was discovered by Wilhelm Tempel in 1867.

-Has a mass of 370 kg

-Was traveling at a rate of 68,800 mph when Deep Impact hit it.

Deep Impact

-Deep Impact was a spaceship created by NASA to explore a Comet!

-Deep impact was used to see not only the outside of Tempel 1 but the inside too.

-Unfortunately, taking pictures of the inside of Tempel 1 was very difficult and expensive for the Deep Impact Mission.

-It took 6 YEARS to reach Tempel 1 in the Kuiper Belt.

-July 4th 2005 the spacecraft Deep Impact landed on Comet Tempel 1.

Other Facts

The Coma of a Comet is made of gas and dust; the stuff on the outer layer of a comet that melts when it goes near the sun.

Deep Impact was released in Pasadena, California.

Like everything else in the Kuiper Belt, Comets are waste particles of planets formed billions of years ago and were pushed further out into our Solar System.
