So this comet was recently discovered, but scientist say it last came 50,000 years ago.
How do we know this?
Thanks in advance!

There are several methods that scientists use to date space material such as comets. One common method is radiometric dating, which involves measuring the relative abundances of certain radioactive isotopes and their decay products in a sample. This can be used to determine the age of rocks and other materials on Earth, as well as objects in space such as comets and asteroids. Another method is called crater counting, which involves counting the number of impact craters on a surface and using this information to estimate the age of the surface. This method is commonly used to date surfaces on planetary bodies such as the Moon and Mars, as well as on smaller objects like comets and asteroids.
