Question: How far away is the mar's moon, Phobos, away from earth?
I need it! ! 10 points to the best answer!!!!!!!!!!!!!!!
If you can figure it out try here
Roughly 3700 miles... but could be as much as 4900 miles or as little as 1800 miles, due to the orbital nature of the two bodies.
"Distance from Earth varies from 36 million miles (nearest planet after Venus) to over 250 million miles. Proportionately, this six-fold distance variation is the greatest of any planet."
phobos, being fairly close to the planet would be the same.
Same as Mars plus or minus a little bit. The variations in the distance of Mars make the distance to Phobos completely irrelevant. Phobos is the same sort of distance from Mars as an artificial satellite orbiting Earth.
<Sigh>OK. Mars is an average of 1.524 au, which is 227 939 100 km from the sun, with an aphelion of 1.666 au, and Phobos is an average of 9377 km from the centre of Mars. The maximum distance would therefore be 150 million + 250 million + 9377 km. Do you see the issue? The difference Phobos makes is absolutely tiny.
No where near best answer!!!!
that depends on the day...
mars isn't always the same distance from the earth. likewise, mars's moon orbits around mars, so it goes doubly so.
Phobos goes round the mars in .3 days at a height of 9380kilometers from Mars center.
The earth Mars distance varies always
The distance is always changing, as is the distance to Mars itself.
