2024年1月26日 · The orbital period of Mars, is, as anyone can find at Wikipedia, $T=686.98$ d, and the semi-major axis of its orbit is $a=2.2794\cdot10^{11}$ m.

2014年7月6日 · Kepler did know the orbital period of the Earth, Mars, Venus, Mercury, Jupiter, and Saturn. He had access to observations going back centuries, including Brahe's most excellent data. What couldn't know was the absolute size of the Earth's orbit, so the best he could do was give the size of the plantets' orbits in terms of the Earth-Sun distance ...

The Moon has an orbit period of 27.3 days and an orbital radius of 3.84\times 10^8 m. The average orbital radius (semi-major axis) of the orbit of Ceres, an asteroid circling the Sun between Mars and Jupiter, is 2.77 AU.

There are two answers to this, because the period "687" was known long before it was recognised as an "orbital period". The Babylonians knew by 600 BCE that Mars took 79 years to go through all 12 constellations 42 times, giving a period of 79/42 × 365.25 = 687 days.

A satellite on a circular orbit of radius R around Mars has an orbital period of 10.0 hr. A second satellite is to be placed in a circular orbit so that its orbital period will be 5.00 hr. The radius of the orbit of the second satellite should be closest ; Mars orbits the Sun at a mean distance of 228 million km, in a period of 687 days.

Saturn orbits the Sun at an average distance of 1.4 billion km. Calculate the orbital period of Saturn. Mars has a small moon named Deimos, that orbits it with a period of 30 hours, 21 minutes. The radius of Deimos' circular orbit around Mars is 2.35 x 10^4km. Use this information to calculate the Qualitative Representation.

What is Mars' orbital period? What is the period (in hours) of a satellite circling Mars 100 km above the planet's surface? The mass of Mars is 6.42 times 10^23 kg, its radius is 3.40 times 10^6 m, and G = 6.67 times 10^-11 N cdot m2/kg2.

The mean distance between the center and the center of the moon is 3.84x10^8 m and the moon has an orbital period of 27.3 days. Find the distance from earth of an artificial satellite that has an orbital period of 9.1 days. Convert the period of Mars's orbit T_{Mars} = 1.88 y to SI units, where we take 1 y = 365.25 days.

Find its orbital period. Mars has two moons, Phobos and Deimos. It is known that the larger moon, Phobos, has an orbital radius of 9.43 \times 10^6 m and a mass of 1.13 \times 10^{16} kg. Find its orbital period. Mars makes one complete orbit of the Sun every 1.88 years. Calculate the radius of the orbit of Mars.

Mars has a moon (Phobos) with an orbital period of 7.67 hours and an orbital radius of 9.4 x 106 m. Use Kepler's 3rd Law to estimate the mass of Mars. Mars orbits the Sun at a mean distance of 228 million km, in a period of 687 days.
