Why is Clavius an old crater?
Clavius’ location toward the southern limb of the Moon causes it to appear oblong due to foreshortening. Clavius is one of the older formations on the lunar surface and was likely formed during the Nectarian period about four billion years ago. Despite its age the crater is relatively well-preserved.

How did NASA find water on the moon?
In 2009, NASA launched the Lunar Reconnaissance Orbiter (LRO). It also detected water ice on the Moon’s poles using the onboard radar, ultraviolet detector as well as the neutron spectrometer. LRO has been orbiting the Moon for over a decade now, longer than any other orbiter.
Where can I find Clavius crater?
Clavius is among the largest and oldest craters on the Moon. Located in the far southern area of the Moon’s near side, it’s visible in binoculars and small telescopes between first and third quarter phases.
What is the deepest crater on Earth?
Vredefort crater
The Vredefort crater /ˈfrɪərdəfɔːrt/ is the largest verified impact crater on Earth. It was 160–300 km (99–186 mi) across when it was formed; what remains of it is in the present-day Free State province of South Africa.
Are there bottomless craters on the moon?
No, but there is an interesting feature of the Moon that could serve to explain the misunderstanding. Near the south pole of the Moon a few dark craters with pronounced rims can be found. They are pretty deep (although not bottomless), and very, very dark.

Where is Clavius located on the Moon?
Clavius’ location toward the southern limb of the Moon causes it to appear oblong due to foreshortening. Its great size makes it visible to the unaided eye as a prominent notch in the terminator about one to two days after the Moon reaches first quarter.

Lunar Orbiter 4 view of Clavius. Clavius is one of the largest crater formations on the Moon, and it is the second largest crater on the visible near side (very close in size to Deslandres). It is located in the rugged southern highlands of the Moon, to the south of the prominent ray crater Tycho.
What is the floor of Clavius like?
The floor of Clavius forms a convex plain that is marked by some interesting crater impacts. The most notable of these is a curving chain of craters that begins with Rutherfurd in the south then arcs across the floor in a counterclockwise direction forming a sequence of ever diminishing diameters.
