Nasa Answers Your Questions about Coment Elenin
"Often, comets are portrayed as harbingers of gloom and doom in movies and on television, but most pose no threat to Earth. Comet Elenin, the latest comet to visit our inner solar system, is no exception. Elenin will pass about 22 million miles (35 million kilometers) from Earth during its closest approach on Oct. 16, 2011.

Also known by its astronomical name C/2010 X1, the comet was first detected on Dec. 10, 2010 by Leonid Elenin, an observer in Lyubertsy, Russia, who made the discovery "remotely" using an observatory in New Mexico. At that time, Elenin was about 401 million miles (647 million kilometers) from Earth. Since its discovery, Comet Elenin has – as all comets do – closed the distance to Earth's vicinity as it makes its way closer to perihelion, its closest point to the sun.

NASA scientists have taken time over the last several months to answer your questions. Compiled below are the some of the most popular questions with answers from Don Yeomans of NASA's Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and David Morrison of the NASA Astrobiology Institute at the NASA Ames Research Center in Moffett Field, Calif."


Then they have a whole list of questions, answers, etc.. This is an example of one such question:

Q:"Will Comet Elenin come close to the Earth or between the Earth and the moon?"

A: "Comet Elenin will not come closer to Earth than 22 million miles (35 million kilometers). That's more than 90 times the distance to the moon."

Something about that answer, and all others, feels incomplete, but that is just my opinion.

This Nasa FAQ also states the Earth is 250,000 miles from the Sun. That is incorrect by 157 million miles. Maybe the rest of it is similarly inaccurate

The comet wasn't discovered in 2010. Nasa have known about it for ages.

Don't believe anything nasa says.

show a link where it says that and your numbers are just a tad off too.

The Earth’s average distance from the Sun, which astronomers call the semimajor axis, is 92.96 million miles.



But remember that this is an average number. The Earth actually follows an elliptical path around the Sun. At the closest point of its orbit, called perihelion, the Earth is only 91.40 million miles. And then when it’s out at the most distant point of its orbit, called aphelion, the Earth reaches 94.51 million miles.
