How old is the Clavius crater?
Clavius Crater is located in the southern part of the visible hemisphere of the Moon. The crater was formed during the Nectarian period, that is, its age is more than 3.85 billion years. The crater has a diameter of 230 km and a depth of 4.9 km.
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.
Where is the 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. It’s perhaps best known as the site of the fictional Moon base in Stanley Kubrick’s movie 2001: A Space Odyssey.
How big is the Clavius crater?
Clavius is the third largest crater on the visible near side of the Moon and also one of the oldest lunar craters. Clavius measures about 225 km (140 mi) across and was formed by an asteroid impact some 4 billion years ago.
Why can we not see the South Pole Aitken basin from Earth?
The South Pole-Aitken basin is oval-shaped, as wide as 1,600 miles (2,500 km) and 8.1 miles (13 km) deep. Despite its size, it cannot be seen from Earth because it is on the far side of the Moon. To measure subtle changes in the strength of gravity around the Moon, Dr.

Are there any craters on the lunar surface?
Crater Tycho taken by the Hubble Space Telescope. This is a list of named lunar craters. The large majority of these features are impact craters. The crater nomenclature is governed by the International Astronomical Union, and this listing only includes features that are officially recognized by that scientific society.
When did Christopher Clavius use the decimal point?
He used the decimal point in the goniometric tables of his astrolabium in 1593 and he was one of the first who used it in this way in the West. As an astronomer Clavius held strictly to the geocentric model of the solar system, in which all the heavens rotate about the Earth.
