Grigg is a lunar impact crater that is located on the far side of the Moon. It lies in the northern outskirts of the huge walled plain Hertzsprung, to the southwest of the crater Fersman and southeast of Poynting. The rim of this crater is generally circular, with a small impact crater intruding into the eastern edge. A small crater fills the northwestern part of the interior floor.

Grigg was named after New Zealander astronomer John Grigg by the IAU in 1970. [1]

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Grigg.

<span class="mw-page-title-main">Carrillo (crater)</span> Crater on the Moon

Carrillo is a small lunar impact crater located near the eastern limb of the Moon. In this location the crater is subject to lunar libration effects, and appears highly oval due to foreshortening. It is located on the slope of highlands on the west side of Mare Smythii, and its inner wall is wider on the western side than to the east.

Arrhenius is a lunar impact crater that is located just on the far side of the Moon, near the southwest limb. In this location the vicinity of the crater can be viewed during favorable librations, although it is viewed from on edge. To the south-southeast is the worn crater Blanchard, and De Roy lies further to the west.

<span class="mw-page-title-main">Artamonov (crater)</span> Crater on the Moon

Artamonov is a lunar impact crater on the far side of the Moon. Its eroded outer rim does not have the circular shape of most lunar craters, but the overall shape of three or four merged craters. The largest is in the south, with smaller circular bulges to the north and east.
