The main crater is Caloris Basin.
Caloris Basin I think is the deepest and the youngest too.
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 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.
There are no craters on Neptune because its made almost entirely of gases.
== == That would be the craters on its surface, particularly the Caloris Basin, a 1500 km impact crater.
The Caloris Basin, also called Caloris Planitia, is a about 1,550 km (963 mi) in diameter.
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.
Mercury
Yes, Mercury has a large cratered surface due to impacts from asteroids and comets. The largest known crater on Mercury is the Caloris Basin, which is about 960 miles (1,550 kilometers) in diameter.
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.
Some important landmarks on the planet Mercury include the Caloris Basin, a large impact crater with extensive radial patterns, and the Rachmaninoff basin, a relatively young crater with unusual dark material. Mercury's scarps, tall cliffs thought to be caused by the planet's shrinking, are also notable landmarks.
