The "Good News"
Russian scientists say an asteroid on a collision course with Mars, will not affect Earth if it hits the 'Red' planet in January 2008.

:huh:
Just how big of an impact would it be to affect the earth?

The estimated 3 megatons of energy from the asteroid Mars collision seems a little small to affect the earth.

The "Bad News"
Asteroid to miss Mars, may hit Earth

:popcorn:
Will this be before or after the sun goes nova in 5 billion years?

It wouldn't affect Earth at all. However if Mars were annihilated there would be consequencies for us.

A 3 megaton impact on Mars is only a 1 mile diameter crater.



barely any consequences even for Martians.

Meteor Crater in Arizona was a 2.5 megaton impact.

Mars! :-P  here's a link to the high res image.

This perfectly formed crater on Mars northern Elysium Planitia is a little more than twice the diameter of Meteor Crater in Arizona. Picture from Mars Orbital Camera taken July 1998.

Must have been a right angle impact. No sign of oblique angle debris scatter.

"Happy Face Crater" (officially known as Galle Crater)



I think it looks like Blossom!
