- An exoplanetary system has two known planets. Planet X orbits in 290 days and Planet Y orbits in 145 days. Which planet is closest to its host star? If the star has the same mass as the Sun, what is the semi-major axis of the orbits for Planets X and Y?No handwrittenThe ratio of charon to pluto's roche limit? or How close is Charon to Pluto's Roche limit? please solve accurate and exact
- What is the angular diameter of Saturn (in arc seconds) as seen from Earth when the two planets are closest together? ( Hint: Use the small-angle angular diameter (in arc seconds) linear diameter formula, 2.06 x 105 distance 19.99 X arc seconds What is the angular diameter of Saturn (in arc seconds) as seen from Earth when the two planets are farthest apart? 20 X arc secondsThere is strong evidence that Europa, a satellite of Jupiter, has a liquid ocean beneath its icy surface. Many scientists think we should land a vehicle there to search for life. Before launching it, we would want to test such a lander under the gravity conditions at the surface of Europa. One way to do this is to put the lander at the end of a rotating arm in an orbiting earth satellite.Why is almost every solid surface in our solar system scarred by craters?

Read ItUF, s In 2014, astronomers discovered 22 new KBOS, among those the following three: 2014 with a period of 331.1 years; 2014 TT, with a period of 280.8 years; 2014 QM with a period of 315.2 years. Given that information and knowing that Neptune's period is 85 441 164.8 years, which of those objects - if any- are likely part of the Plutino family of KBOS?
