Bad Astronomy | Exoplanet YSES 2b is much farther from its star than expected

A team of astronomers has targeted 70 nearby stars to look for such exoplanets, and have just announced a new one: YSES 2b, a giant planet orbiting a star just 360 light years away. We ve seen some similar to this before, but in this case, this planet is special. For one thing, it s orbiting a star that will one day be very much like the Sun. For another, it s orbiting at least 16.5 billion kilometers from the star, a whopping 110 times farther from its star as Earth is from the Sun! That s a very, very long way, and what it s doing that far out is a mystery.
