Predict/Calculate (a) If you want to launch a probe that orbits the Sun with a period of 2.00 years, what should be its orbital radius? Give your answer in astronomical units. The astronomical unit AU is defined as the mean distance from the Sun to the Earth (1 AU = 1.50 × 10 11 m). (b) Is the orbital speed of this probe greater than, less than, or equal to the orbital speed of the Earth? Explain. (c) What is the orbital speed of this probe?

According to Lunar Laser Ranging experiments the average distance LM from the Earth to the
Moon is approximately 3.85 x 105 km. The Moon orbits the Earth and completes one revolution
in approximately 27.5 days (a sidereal month).
a) Calculate the orbital velocity of the Moon.
b) Calculate mass of the Earth.
6.) Planet X has 10 times the mass of the Earth’s mass. The star that it orbits has the same mass as our Sun.The planet average distance from its star is 2.5826 (10)11 ??.a) What is the gravitational force between Planet X and its star in units of Newtons?b) What is the velocity of Planet X as it orbits its star in units of metres per second?
