Well the earth is 93 million miles from the sun. Mars is 142 million miles from the sun. At their closest they're about 50 million miles apart, but because they go around the sun at different rates they're much farther apart most of the time.
So to answer your question. Is that very near. I would say no. It is near, but not very near.
Mars is still very near the Sun this month, having just passed a conjunction; that means that Mars and the Earth were on opposite sides of the Sun.
Mars is very similar to Earth. Mars' year and day are very similar to Earth compared to other planets.
Mars can teach us alot about the earth. Mars is a very pretty planet and Mars is very red but like the moon but very diffrent but some like the earth but with out life on it but very rocky and has craders in it but nothing like the earth but not as we know it.
No, Mars is in a stable orbit, and isn't going to come anywhere near Earth.
Mars
they will be very close but they will not hit each other.
earth is on one side of mars. Jupiter is on the other. (bare in mind, there is a asteroid belt between mars and jupiter) And said Asteroid Belt used to be a planet. Poor Maldek, smashed by the crazy Martians :-)
Venus and Mars Mars is more closer... What has that mean?? To answer your question, Venus and Mars are close to Earth.
mars
Moon Near-Earth Objects (asteroids, comets) Venus Mars
Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune [Pluto] So answer is Mars and Saturn
The rotation of Mars is very similar to the rotation of earth. Its axial tilt, the length of its day, and the direction of its rotation are all very similar to those of earth.
