The orbital period of Mars is 687 Earth days, or 1.88 Earth years. The planet’s orbital period is similar to Earth’s, and it is slightly bigger than our planet—but still less than twice the size. Answer to: Planet X has 20 times the mass of the earth and four times the earth's radius. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun as seen in the graph above. Moreover, the orbital period of KOI-456.04 around its Sun-like star is almost identical to an Earth year.

It has an orbital period of approx. Mercury: 87.97 days (0.2 years) Venus : 224.70 days (0.6 years)

The study, which was recently published in the journal Astronomy & Astrophysics , was led by astrophysicist René Heller of the Max Planck Institute for Solar System Research in Germany.

Tiny variations in the orbital period of planet Kepler-160c gave scientists the hint of a third planet. a) What is the orbital period of Planet {eq}X {/eq} in years? Kepler-160 has been known for about six years to be a host star of two exoplanets, called Kepler-160b and Kepler-160c. Both these planets are substantially bigger than Earth and in relatively close orbits around their star. An Earth planet twice the mass of the Earth and orbiting 1 AU away from a star just like the Sun, the planet would still orbit at 66,705 mph, but have an orbit 564 miles less wide than the real Earth's. To put it simply, Mercury has an orbital period of 88 days (87.969 to be exact), which means a single year is 88 Earth days – or the equivalent of about 0.241 Earth years. And it has an orbital period around the star of 378 days, similar to the Earth year it takes to complete an orbit around the sun. No planet has exactly twice the Earth's period of revolution. Suppose a planet with the same mass as Earth orbits at a distance of 1 AU from the star. The precise amount of time in Earth days it takes for each planet to complete its orbit can be seen below. Kepler-160 has been known for about six years to be a host star of two exoplanets, called Kepler-160b and Kepler-160c. Some 3,000 light years away from Earth, researchers believe they have found an Earth-size exoplanet orbiting a sun-like star. The precise amount of time in Earth days it takes for each planet to complete its orbit can be seen below. Both these planets are substantially bigger than Earth and in relatively close orbits around their star. But this time, they have found an exoplanet having quite bizarre characteristics. Imagine another solar system, with a star more massive than the Sun. The fastest orbiting planet in our Solar System is Mercury. It has an orbital period of approx. What is the planet's orbital distance?
