Nearly all planets that astronomers have found orbiting other stars have been giant planets with masses more like Jupiter than Earth, and with orbits located very close to their parent stars. Does this prove that our Solar System is unique? Explain your answer.
Does the Kepler's Third Law of planetary motion applies to Pluto? Explain

- Why do we think that planets in our Solar System were not formed out of the gaseous disk by direct gravitational collapse? Planets are formed in disks. Disks rotate too fast to collapse gravitationally to form planets. In disks that are not massive enough, tidal gravity of the central star prevents the disk gas from collapsing. The material in the disk orbits close to the star. This makes the disk too hot, and pressure support prevented the disk from gravitational collapse. The gravity of the forming planets was not enough to accrete gas.arrow_forwardImagine a trans-Neptunian object with roughly the same mass as Earth but located 50 AU from the sun. a) based on the solar nebula theory, what do you think this object would be made of and why? b) on the basis of speculation, assume a reasonable density for this object and calculate its diameter in units of Earth radii.arrow_forwardImagine that astronomers have just discovered a planet orbiting another star (other than the Sun), and they have reported the mass of the planet as 4.2 Jupiter-masses.
