Briggs (crater)
Encyclopedia
Briggs is a lunar
crater
that is located in the western part of the Oceanus Procellarum
, to the east of the large walled plain Struve
. It lies to the northeast of the walled plain Eddington
, and north-northwest of the crater Seleucus
. The isolated position of this crater on the mare, near the northwestern limb of the Moon
, makes it relatively easy for an Earth
-bound observer to locate. The crater is named after the English mathematician Henry Briggs
.
The outer rim of Briggs is not quite circular, with outward bulges to the north-northeast and southward. At the mid-point of the crater floor is a central ridge, extending to the north.
Moon
The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...
