There is a star in the constellation of Pegasus that is 129 light years from Earth. It’s a young star, a mere 50 million years old (cf the sun is 4.5 billion years old (ish) This star, HR 8799, has planets, hot planets far bigger than Jupiter and Saturn that swing around it in vast orbits.
The orbits are not complete, of course, the scientists have only been watching the system since 2009. A year on the closest planet to the star lasts 40 earth years, the most distant planet takes 400 earth years to do a complete circuit.
OMG.
