A planet is discovered to orbit around a star in the galaxy Andromeda, with the same orbital diameter as the Earth around our Sun. If that star has 4 times the mass of our Sun, what will the period of revolution of that new planet be, compared to the Earth's orb o One-fourth as much o One-half as much Twice as much A. Four times much The average distance from the Earth to the Sun is defined as one "astronomical...
points A newly discovered planet is in a circular orbit around a distant star with an orbital period of 400 Earth days. The planet also rotates on its axis, making one full rotation every 4.00 Earth days. The radius of the planet is rp = 7.00 × 106 m and the radius of the planet's orbit about the star is r 7.00×1011 m. My Notes Ask Your Tea Determine the ratio of the radial acceleration, due to the rotation of...
46. A certain planet is in circular orbit about a star. The radius of the orbit is 9.20x10 kilometers. The planet requires 8.76x10' hours to complete one orbit. Calculate the centripetal acceleration of the planet in units of m/s
2. A new Earth-like planet is found orbiting a distant star with a circular orbit. The it takes 1.3 Earth years for the planet to make a full circle around it's star. The star has a radius 5 x 1011m. The altitude of the planet's orbit is 8 x 105 km. Find the mass of the star that the new planet is orbiting.
Astronomers discover an exoplanet (a planet of a star other than the Sun) that has an orbital period of 3.97 Earth years in its circular orbit around its sun, which is a star with a measured mass of 3.41 times 10^30 kg. Find the radius of the exoplanet's orbit. _____ m
5) A satellite in a circular orbit of radius R around planet X has an orbital period T. If Planet X had one-fourth as much mass, the orbital period of this satellite in an orbit of the same radius would be: A) 2T B) T square root(2) C) T/4 D) T/2 E) 4
A new planet has been discovered that has a mass one-ninth that of Earth and a radius that is eight times that of Earth. Determine the free fall acceleration on the surface of this planet. Express your answer in the appropriate mks units. A new planet is discovered orbiting a distant star. Observations have confirmed that the planet has a circular orbit with a radius of 10 AU and takes 198 days to orbit the star. Determine the mass of...
Astronomers discover an exoplanet (a planet of a star other than the Sun) that has an orbital period of 3.77 Earth years in its circular orbit around its sun, which is a star with a measured mass of 3.79 x 1030 kg. Find the radius of the exoplanet's orbit. radius:
planet X travels in a circular motion orbit around the Sun. The radius of Planet X is twice that of Earth. The year on Planet X is 540 Earth years. The mass of Planet X is half that of Earth. The mass of the sun is 1.99*10^30 kg. The Earth's orbital distance from the Sun is 1.50*10^11 m.
Astronomers discover an exoplanet, a planet orbiting a star other than the Sun, that has an orbital period of 4.01 Earth years in a circular orbit around its star, which has a measured mass of 3.97X10^30. Find the radius of the exoplanet's orbit.
