1. (6 points, 3 for each answer) Planets are easier to detect around
... Planets are easier to detect around low mass stars because a planet with a given mass causes a star with a lower mass to move more quickly than one with a higher mass. This can be seen using the momentum-conservation equation V∗ = Mp Vp /M∗ . As M∗ decreases, V∗ must increase, and that makes the cha ...

The rocky material first accretes solid material to become planetesimals and then with its gravity it will collect the gasses around making them a giant like Jupiter.

... • Left over stuff is still flying around out there – these asteroids, meteoroids and comets still make impacts. • The asteroid belt is a large collection of asteroids. A theory, which is most favoured, is that the proximity to Jupiter tore apart a planet that was forming there. • Starting at about P ...
