We’ve discussed some classes of planet that are pretty strange: hot super-Earths, hot Jupiters and eccentric gas giants. But that was just the warm-up. In this post we’ll check out three more extra-weird ones. First up: Tatoine planets. In case you are less nerdy than you should be, Tatooine is where Luke came from in … More Three more planetary stooges
Hot Jupiters: check. Super-Earths and mini-Neptunes: check. Up next is another unusual class of planet. But what is different is not these planets’ physical properties but the shapes of their orbits. Time to get technical. An orbit is the path a planet follows around its star. The simplest orbit is a circle with the star … More HD 80606: a gas giant on a super-eccentric orbit
It’s official: you are weird. It’s nothing personal, you can’t help it. You live in a weird Solar System. It’s just not like other planetary systems. It’s just not SUPER enough…. Most Sun-like stars have a planet orbiting close-by. Not a hot Jupiter — those are rare. Planets just a little bigger than Earth are … More Hot Super-Earths (and mini-Neptunes)!
Let’s meet a planet called WASP-12b. [Before you ask, extra-solar planets are named based on how they were discovered or their catalog number. Wasp-12b is the twelfth found by the WASP (“Wide Angle Search for Planets”) survey. The “b” indicates that the object is a companion; Wasp-12 itself is the planet-hosting star.] WASP-12b is a … More Wasp-12b: a hot Jupiter
