Radio de Hill
Objects in the solar disc grow by accretion increasing their gravitational influence over the surrounding material. The Hill radios will define the distance around which the planet, in growing or full grown, will capture any object that is inside this distance. In the video I develop the notes for this distance.
The video is in Spanish language, but can be follow by English speaking viewers as well.

This second short video is to remove a possible misunderstanding in the use of the radios of the Sun in two different contexts. Sorry for the possible confusion; I thought better to publish this second video, instead of taping a new one.
