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 Caloris Montes on Mercury.
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.
You could be asking about the element Mercury or the planet Mercury. The element Mercury is probably most remarkable for being a metal which is liquid at room temperature.However, I think this is about the planet. The planet's famous feature is called the "Caloris Basin".AnswerThe first answer asked a good question regarding the "Mercury" of which you write. I'll assume it is the element mercury. I agree with the above. Also, it changes in volume quite a bit with changes in its temperature. That makes it a good filling for a thermometer. Now, I think they use alcohol. Silver colored material in a thermometer is mercury; red is alcohol of some type.Another well-known feature of mercury is that it is heavy compared to other liquids. This is detectable just by holding a container with mercury in it.I believe that it has a high surface tension; that's why it "balls up" when free to sit on a surface.Another feature is that it is a toxin found in polluted streams and thus the creatures that live in these streams. It is considered poisonous and absorbable through the skin, I think.Lastly, it will dissolve gold; keep it off your rings.
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.
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.
The Caloris Basin, also called Caloris Planitia, is a about 1,550 km (963 mi) in diameter.
Mercury
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.
It is approx 1550 km.
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 main crater is Caloris Basin.
I think the answer is the "Caloris Basin".
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.
Caloris Basin is located on the planet Mercury. It is one of the largest impact basins in the Solar System, measuring approximately 960 miles (1,550 km) in diameter.
Mercury doesn't have many geographically distinct features but it does have a feature called the Caloris Basin. The Caloris Basin is one of the largest meteor impact basins in the Solar System. It measures at about 1,550 kilometers or 960 miles in diameter. Since the Caloris Basin is the largest feature on Mercury it is also it's longest.
The Caloris Basin on Mercury is certainly one of the largest impact craters in the Solar System. As to the largest in the Milky Way - you'll just have to wait and see.
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.
