With the GRAIL data, the astronomers were able to map the gravity field both in and around over 1,200 craters on the lunar far side. This region--the lunar highlands--is our Moon's most heavily cratered, and therefore oldest, terrain. Heavily cratered surfaces are older than smoother surfaces that are bereft of craters. This is because smooth surfaces indicate that more recent resurfacing has occurred, erasing the older scars of impact craters.
Ganymede: Ganymede is both the largest moon of Jupiter, our Solar System's planetary behemoth, as well as the largest moon in our entire Solar system. Observations of Ganymede by the HST in 2015 suggested the existence of a subsurface saline ocean. This is because patterns in auroral belts and rocking of the magnetic field hinted at the presence of an ocean. It is estimated to be approximately 100 kilometers deep with a surface situated below a crust of 150 kilometers.
Moon in Earth (Taurus, Virgo or Capricorn) will be in their element when they are making money, adding to their resources or making their home cosy, comfortable or beautiful. They cannot just wish or believe, they need to have and to hold the tangible or to make progress in order to feel secure. They react in a grounded, steady and matter- of-fact manner, which can turn into stubbornness and a reluctance to change or let go. They are very much at home when working or being productive in their practical way.
