What created Orientale Basin on the Moon?
The basalt in the central portion of the Orientale basin is probably less than 1 km (0.62 mi) in thickness which is much less than mare basins on the Earth-facing side of the Moon. The collision caused ripples in the lunar crust, resulting in the three concentric circular features.
What is a basin on the Moon?
Basins are giant craters larger than 300 km that have two or more concentric rims and no central peak. The easiest basin structure to see on the near side of the Moon surrounds Mare Nectaris. The Altai Scarp is a very prominent piece of the main 860 km wide rim of the Nectaris impact basin.
What is unique about the Mare Orientale?
Located along the Moon’s southwestern limb — the left-hand edge as seen from Earth — Orientale is the largest and best-preserved example of what’s known as a “multi-ring basin.” Impact craters larger than about 180 miles (300 kilometres) in diameter are referred to as basins.
How was Mare Orientale formed?
Only partially flooded by lava the Mare Orientale is over 3 billion years old, about 600 miles (950 kilometers) across and was formed by the impact of an asteroid sized object. The collision caused ripples in the lunar crust resulting in the concentric circular features.
Where is Shackleton crater located?
south pole of the Moon
The Shackleton crater lies at the south pole of the Moon. The pole lies within the rim of the crater, and is only a few kilometers from the mid-point. From the perspective of the Earth, this crater lies along the limb of the Moon, making observation difficult.
What is the biggest crater on Mercury?
the Caloris basin
The crater, discovered in 1974, is surrounded by the Caloris Montes, a ring of mountains approximately 2 km (1.2 mi) tall….Caloris Planitia.

What is the largest basin on the moon?
The South Pole-Aitken
The South Pole-Aitken (SPA) basin is the largest and oldest recognized impact basin on the moon. It’s diameter is roughly 2,500 km or 1,550 miles. The moon’s circumference is just under 11,000 km, meaning the basin stretches across nearly a quarter of the moon.
How old is Imbrium basin?
about 3.85 billion years ago
The Imbrium Basin is also the second youngest basin on the Moon. Based on samples returned by Apollo 15, it formed about 3.85 billion years ago.
What’s the name of a female horse?
mare
form and function. …male horse is called a stallion, the female a mare. A stallion used for breeding is known as a stud. A castrated stallion is commonly called a gelding.
Is Shackleton crater visible from Earth?
Description. The rotational axis of the Moon passes through Shackleton, only a few kilometers from its center. The crater is 21 km in diameter and 4.2 km deep. From the Earth, it is viewed edge-on in a region of rough, cratered terrain.
Is there a Shackleton crater on the Moon?
The scientists investigated Shackleton Crater, which sits almost directly on the moon’s south pole. The crater, named after the Antarctic explorer Ernest Shackleton, is more than 12 miles wide (19 kilometers) and 2 miles deep (3 km) — about as deep as Earth’s oceans.
What element makes Mars red?
iron
A Layer of Dust Wind eroded these surface rocks and soil, and ancient volcanos blew out the iron, spreading it all over the planet. When this happened, the iron within the dust reacted with oxygen, producing a red rust color. So, Mars is red because it has a layer of rusty dust covering its entire surface!
