What planet has a year roughly twice as long as Earth's year?
Mars.
From Kepler's third law a hypothetical planet that is twice as far from the sun as the earth should have a period of?
Kepler's third law states that the square of the orbital period of a planet is proportional to the cube of its semi-major axis. If a hypothetical planet is twice as far from the sun as Earth, its semi-major axis would be 2 times larger. Therefore, the period of this hypothetical planet would be √(2^3) = 2.83 times longer than Earth's period.
If a planet with twice the mass of earth orbiting a star with the same mass as the sun and an orbital distance of 1AU what is the orbital period?
The orbital period of a planet can be calculated using Kepler's Third Law, which states that the square of the orbital period is directly proportional to the cube of the semi-major axis of the orbit. For a planet with twice the mass of Earth orbiting a star with the same mass as the Sun at a distance of 1AU (Earth-Sun distance), the orbital period would be the same as Earth's, which is about 365 days.
What planet has seasons like earth but they are twice as long?
Mars
If a planet has two moons and one moon twice as far from the planet as the other which moon would complete a revolution of the planet first?
The moon closer to the planet would complete a revolution first, as it would need to cover a shorter distance in the same amount of time compared to the moon that is twice as far away. This is due to the fact that the closer moon has a smaller orbit and shorter path around the planet.
What planet has twice the earth's period of revolution?
Mars has an orbital period of very approximately twice that of the earth
What planet has twice the earth's period are re volution?
The planet that has a revolution period twice that of Earth is Mars. It takes Mars approximately 687 Earth days (or about 1.88 Earth years) to complete one orbit around the Sun.
Which of these planets has twice the earth's period of revolution?
Saturn has a period of revolution that is approximately twice as long as Earth's. While Earth takes about 365 days to complete one revolution around the Sun, Saturn takes roughly 29.5 Earth years to complete its orbit.
What planet has a year roughly twice as long as Earth's year?
Mars.
Which planet has a year which is twice the length of an earth year?
Mars with an orbital period of 1.88 years.

What planet is twice the size of earth?
No planet.
What is mercury's period of revolution?
Mercury takes 88 Earth days to go around the Sun, but strangely, its day is twice as long taking 176 Earth days to rotate just once! Mercury's slow spin is evidence of why the planet has a magnetic field just 1% as strong as Earth's. (This may have been a very long answer)

Mars
What is mercury's length of revolution?
Mercury completes an orbit of the Sun in 88 Earth days, which is about 3 months or 0.24 Earth years. The slowly spinning planet makes only 1.5 rotations per revolution, giving a sidereal day of 58.6 Earth days but a solar day, sunrise to sunrise, of 176 Earth days (twice as long as its year).
What would appear different about the moon if it rotated twice during each revolution?
If the moon were to rotate twice during each revolution, the tides on the Earth would appear different. Also, the moon itself would show its far side rather than having the same side facing the planet all the time.
