98.59

Lunar crater Theophilus is a circular depression in the floor of the Moon near the visible moon center. He - like many so-called Ring Mountain - a high annular wall ( crater rim ) and in the middle of a group of central mountains. It is named after Theophilus of Alexandria.

Its diameter is 105 km, its Wall height over six kilometers. It had been previously thought due to its form, that he is of volcanic origin, but they are almost all lunar craters caused by meteorite impacts. The asteroid whose impact has raised the mountain ring was about five kilometers in size. By escaping the explosion material, the bottom of the crater is slightly lower than the surroundings.

In selenographic coordinates specified, Theophilus is between 10 ° and 13 ° south latitude, and 25 ° -28 ° east longitude. The inner slope of his Walles has distinct terraces, making it one of the most beautiful moon objects.

In addition to Theophilus is the sine Asperitatis.
