Tycho: Which Crater is it?

85 kilometers in diameter, Tycho refers to the youngest crater of the moon, 4 kilometers deep. It also happens to be one of the brightest yet smallest craters to be found in the third quadrant. Tycho gets its name from a popular astronomer named “Tycho Brahe”. According to the sources, the age of the Tycho is approx 180 million and it has been in the southern lunar highlands since its inception. The area around the lunar crate is filled with different crates, each of varying sizes and shapes. These crates are believed to be overlapping the old crates. Astronauts also believe that some of these crates are developed from the ejecta that is released from the huge chunks of Tycho. The specialty of this youngest crater of the moon is that it is clearly defined, unlike other craters found in space. There are many old craters in the third quadrant of the moon, but nothing looks as sharp and clear as Tycho. Let’s learn more about the lunar craters, their locations, and how they can be seen. Lunar Craters The surface of the moon is covered with many craters, and each one of them is formed by a certain impact. Now, the question is what exactly are these craters? And when were they discovered? Galileo launched his telescope in late 1609 and that was also the time when he used the telescope to get a closer picture of the moon from Earth. That’s when he discovered that the moon does not have a clean surface and a perfect sphere. The surface of the moon had many cup-like depressions that were named “craters”. It is believed that these craters are found in the moon because the moon does not have water, atmosphere, and tectonic plates. Some of these craters are as old as 2 billion years. You can identify the age of one big crater by identifying the smaller craters present in it. The smallest craters that are located in the moon have a microscopic size, which means they are so tiny that it is impossible to view them with the human’s naked eye. These craters have returned to Earth. The larger ones, on the other hand, are as large as 290 kilometers in diameters and are found in the South pole. So, how can you recognize a crater or how do you know that the object you see on the moon is a crater? Well, the crater has certain features that distinguish them from the rest of the elements. Let’s take a look at a few of them:
  • A raised rim
  • A flat and smooth floor that accumulates small craters
  • Central peak (which is part of only some craters)
  • The wall that slopes downwards
A crater can have all or a few of these features, depending on its size, location, and formation. Usually, the age of lunar craters is millions of years. Tycho is a 108 million-year-old crater that is also the brightest and youngest one of all.
