- Approximately how many asteroids that are 0.89 km in radius would it take to make a planet which has a radius of 6590.0 km?At an average opposition, the Earth and Mars are separated by 0.52 AU. Suppose an astronomer observes Mars at opposition and that seeing blurs the images to a resolution of 1.0 seconds of arc. What is the smallest surface feature the astronomer would be able to resolve on Mars? How does this size compare with the diameter of Mars?An asteroid orbits the Sun in a 2:1 resonance with Jupiter. What is its orbital period (in years)? What is its average distance from the Sun (in AU)?
- How deep would be the eclipse caused by Jupiter transiting in front of the Solar disk, as observed from a distant star?Despite being composed primarily of gas, Jupiter and Saturn have large magnetic fields. This is primarily due to the presence of _________________ beneath its cloud tops.The asteroid Ceres has a mass of 9.39 x 1020 kg and an average radius of about 473 km (4.73 x 102 km). What is its escape velocity (in m/s)? 2GM (Hints: Use the formula for escape velocity, V. ; remember to convert units to m, kg, and s.) r m/s Could you jump off the asteroid? Yes No
