How far is Tempel 1 from the Sun?
Its mean distance to the Sun is 3.12 the distance from the Earth to the Sun (3.12 AU, or 466.7 million km) but as it follows quite an excentric orbit (its excentricity is 0.5176), its distance to the Sun varies between 1.506 AU and 4.735 AU It does thus not cross the path of the Earth – located at 1 AU – but does cross …
How far away from our sun is the comet?
The comet’s journey started over 3.7 trillion miles (6 trillion kilometers) away from the sun, or 40,000 astronomical units. The distance between Earth and the sun is one astronomical unit.
Who Discovered comet Tempel 1?

Brian G. Marsden
Tempel 1/Discoverers
Comet 9P/Tempel 1 was discovered on April 3, 1867 by Ernst Wilhelm Leberecht Tempel of Marseilles France while visually searching for comets. The comet was then 9th magnitude and described by Tempel as having an apparent diameter of 4 to 5 arcmin across.
What is the mass of Tempel 1?
Our best estimate is anywhere from 0.1 – 2.5 x 1014 kg. When you think that a kilogram is 2.2 pounds, you can see that Tempel 1 is pretty massive on the scale of something human. On a planetary scale, consider the Earth’s mass, which is about 6.0 x 1024 kg or asteroid Ceres with a mass of 9.445 x 1020 kg.

What is the composition of comets?
Physical characteristics. The solid nucleus or core of a comet consists mostly of ice and dust coated with dark organic material, according to NASA, with the ice composed mainly of frozen water but perhaps other frozen substances as well, such as ammonia, carbon dioxide, carbon monoxide and methane.
What is eccentricity comet?
Comets have very high eccentricity, close to 1. They start very far from the sun, plunge into the solar system, make a close pass, and then zip out again. Halley’s Comet has an eccentricity of . 967, meaning that at aphelion it is 1+e1−e≈60 times farther from the sun than at perihelion.
