Top Results for Impact Basin

On Jupiter's moon Callisto, Valhalla forms a vast impact structure distinguished by rings around a brighter central region. The concentric features extend across thousands of kilometers, making the full ring system much broader than the central impact area alone. Its appearance records how Callisto'...

Concentric mountain rings make Orientale one of the Moon's distinctive large impact basins. Located near the western limb, it is partly hidden from Earth and is more fully revealed by spacecraft observations. The overall basin spans roughly 930 kilometers, far more than the 120 kilometers stated in...

Spread across the Moon's farside, the South Pole-Aitken Basin is an enormous ancient impact basin roughly 2,500 kilometers across. It is among the largest known impact structures in the solar system, but describing it as the largest known crater anywhere is too definite. Its name links the lunar sou...

Rheasilvia occupies a large part of the southern hemisphere of Vesta, an asteroid with a differentiated rocky interior. Approximately 500 kilometers across, the impact basin is remarkable for its size relative to Vesta itself. A prominent central mountain rises inside it, providing a visible record...

Mare Imbrium occupies a broad impact basin on the Moon's nearside and forms one of the large dark areas visible from Earth. A major collision created the basin approximately 3.85 billion years ago. Later volcanic activity filled much of its interior with basaltic lava, producing the mare, or lunar p...

Caloris Basin is a gigantic impact crater located on Mercury’s surface. It represents one of the most significant geological events in the planet's early history, formed approximately 3.8 billion years ago when a massive asteroid struck. The basin measures roughly 1,550 kilometers across and exhibit...

Hellas Planitia is a colossal impact basin located on Mars’s surface. It represents the largest known crater in our solar system, measuring approximately 2300 kilometers across and reaching a depth of 7000 meters. This Noachian-era feature provides scientists with valuable insights into early Martia...

Asgard is a substantial impact basin located on Jupiter’s moon Callisto. It represents one of the largest ancient features on the satellite's surface. The basin’s prominent central palimpsest and extensive multi-ring structure—reaching approximately 1700 kilometers in diameter—offer valuable insight...

Argyre Planitia is a substantial impact basin located within Mars’ southern highlands. This Noachian-era feature, formed approximately 3.9 billion years ago, exhibits prominent mountain ranges shaped by intense geological activity following the Late Heavy Bombardment. The area represents an importan...

Gilgamesh is a massive impact basin located on Jupiter’s largest moon, Ganymede. It represents one of the most significant geological features there, characterized by a prominent central pit and a vast area covered in ejected material. The crater's size – approximately 260 kilometers across – makes...

Isidis Planitia is a vast, northern impact basin within Mars’ Noachian era. Formed by an ancient collision, it represents a significant geological feature and provides context for understanding early Martian history. The area is of particular interest to planetary scientists studying the planet's fo...

Crisium Basin is a substantial lunar crater located on the nearside of the Moon. It’s notable as the formation zone for Mare Crisium, a large dark plain. The basin's size and the historical significance of Luna 24’s exploration make it relevant to planetary scientists studying impact processes and e...

The Serenitatis Basin is a substantial impact basin on the Moon’s nearside. Formed by an ancient collision, it's notable for its expansive size and geological features. The Apollo 17 mission conducted extensive studies of its southwestern region, specifically within the Taurus-Littrow valley. Scient...

The Hertzsprung Basin is an immense impact crater situated on the far side of the Moon. Measuring approximately 570 kilometers in diameter, it is classified as a multi-ring impact basin rather than a standard crater. The interior of Hertzsprung is heavily eroded and contains a distinct peak-ring str...

The Mare Nectaris Basin is an ancient impact basin on the near side of the Moon that was formed when a massive asteroid struck the lunar surface. The impact event serves as the geological marker for the beginning of the Nectarian period, which occurred approximately 3.92 billion years ago. Over time...

Mare Humorum, Latin for the Sea of Moisture, is an ancient impact basin located on the near side of the Moon. The basin has a diameter of approximately 425 kilometers and is characterized by a well-defined ring structure. Its interior was subsequently filled with dark, basaltic lava from volcanic ac...
