A star with half the mass of the Sun has a planet that orbits with an average distance of 0.5 AU from the star. The planet would have an orbital period of:
A planet is located at < - 3×1010, 8×1010, - 5×1010 > m. A star is located at < 8×1010, - 5×1010, 5×1010 > m.
A planet is 8 astronomical units away from the star CELT and moving on an orbit of period 5 years. Another planet is moving with a period of 16 years. What is the average distance of the second planet from the star.
