It is a type of large crater (surface depression or pit) left on the surface of a moon or planet, caused by a large object striking its surface. It may include concentric rings or flows of melted rock.

The Caloris Basin is an impact basin. It is one of the largest impact craters in the solar system. It was created after the heavy bombardment period and is estimated to be 3.8 billion years old.
The largest impact basin in the solar system is the South Pole-Aitken Basin located on the Moon. It is over 2,500 kilometers (1,553 miles) in diameter and is one of the oldest and largest basins known in the solar system.
The South Pole-Aitken Basin is the oldest, largest, and deepest impact feature on the moon, dating back around 4 billion years. It is a massive basin located on the far side of the moon and is approximately 2,500 kilometers in diameter.
Imbrium is a vast lunar basin on the Moon, formed by a large impact event billions of years ago. It is one of the largest impact craters in the Solar System and is easily visible from Earth. The Imbrium basin is filled with dark mare basalt, giving it a distinctive appearance.
Borealis Basin is significantly larger than Hellas Crater. Borealis Basin, located in the northern hemisphere of Mars, spans approximately 8,500 kilometers (5,300 miles) in diameter, making it one of the largest impact features in the solar system. In contrast, Hellas Crater, situated in the southern hemisphere, has a diameter of about 2,300 kilometers (1,400 miles). Therefore, Borealis Basin is much larger than Hellas Crater.
Impact crater is now more prevalently used for the term impact basin.
Caloris basin is found on the planet Mercury. It is one of the largest impact basins in the Solar System, measuring over 1,500 kilometers in diameter. The basin was created by a large asteroid impact early in Mercury's history.
The Caloris Basin on Mercury was most likely created by a massive impact from a large asteroid or meteorite early in the planet's history. The impact caused the surface to fracture and form the distinctive concentric rings seen in the basin today.

The Caloris Basin on Mercury is one of the largest impact craters in the solar system, spanning about 960 miles (1,550 kilometers) in diameter. It was formed by a huge asteroid impact early in the planet's history.
The South Pole-Aitken basin.
The largest impact basin in the solar system is the South Pole-Aitken Basin located on the Moon. It is over 2,500 kilometers (1,553 miles) in diameter and is one of the oldest and largest basins known in the solar system.
South Pole Aitken Basin (diameter 2500km) is not the largest known impact crater. That distinction lies with Utopia Planitia Basin (3500km) on Mars. However, SPA is the deepest known impact basin in the Solar System at 13 kilometers. If proven, the hypothesized Borealis basin, on Mars, would be the largest impact basis, at more than 10000 km in diameter.
The Caloris Basin is a large impact crater found on the planet Mercury, 963 miles in diameter. Its one of the largest craters in the solar system.
The South Pole-Aitken Basin is the oldest, largest, and deepest impact feature on the moon, dating back around 4 billion years. It is a massive basin located on the far side of the moon and is approximately 2,500 kilometers in diameter.
