The red dwarfs are going to live anywhere from, likea a hundred billion years beyond the life of the universe. They've longer lest them down much longer. The solar system is very much unlike the sun in a lot of ways. You now, the whole system goes from mike, and then there's an eight day planet. And then there's a 12 day planet. But if you like to look at the solar system, our closest planet, mercury, is l 88 days.

Recent years have seen a revolution in the study of exoplanets, planets that orbit stars other than the Sun (or don’t orbit stars at all). After a few tentative detections in the 1990s, dedicated instruments in the 2000s have now pushed the number of known exoplanets into the thousands, enough to begin to categorize their distribution and properties. Today’s guest is John Asher Johnson, one of the leaders in this field. We talk about the various different ways that exoplanets can be detected, what we know about them know, and what might happen in the future.
