An ellipse, like all the planets. Just like every other object in orbit around a much larger central mass, Mars travels
in an orbit whose shape is an ellipse.
But the orbit's eccentricity is only 0.094, which means it's so close to being a circle
that you can't tell the difference by looking.
No planets orbit around Mars. There are two moons that orbit around Mars.
Mars to the Sun is about 228 million kilometers
No. A circle is an unstable shape for an object orbiting another. An orbit is between slightly and very elliptical (egg-shaped). If an object is placed in a circular orbit, the orbit will quickly deteriorate to an elliptical orbit. Added: Mar's elliptical eccentricity is rather above average for a planetary orbit. Not quite as large as Mercury, but large enough.
Earth's orbit is closer to the sun than Mars' orbit. Earth takes about 365 days to orbit the sun while Mars takes about 687 days. Additionally, Mars has a more elliptical orbit compared to Earth's nearly circular orbit.
Yes. Earth is closer to the Sun than Mars, so it will have a smaller orbit.
No. Comets orbit the sun. Many asteroids orbit the sun in between the orbits of Mars and Jupiter.
Diemos, the smaller of the two moons of Mars, takes 30.3 hours to make one orbit of Mars.
Mars's orbit is not unusual.
No. Mars is a planet and thus much smaller than any star. Stars cannot orbit planets. However, Mars does orbit the sun, which is a star.
Mars has two small moons named Phobos and Deimos, but no planets orbit it.
The two natural satellites that orbit Mars are Phobos and Deimos.
The asteroid belt orbits the Sun. Phobos and Deimos the moons of Mars orbit Mars.
