Exoplanet Types: Worlds Beyond Our Solar System

When we describe different types of exoplanets – planets outside our solar system – what do we mean by “hot Jupiters,” “warm Neptunes,” and “super-Earths”? Since we’re still surveying and learning about the variety of worlds out there among the stars, it’s sometimes helpful to refer to characteristics they share with planets we’re familiar with in our own planetary system.

  1. NASA throughout my life you have been inspiring me since I was a little kid to any 11 year old now. I am really fascinated by about many exoplanets that you guys have discovered so far! Keep up the great work for the humanity !

  2. I always knew, since I was a kid that planets in our solar system are but one possible variation in a multitude of others when scientists where still arguing whether there are other planets in the universe or not. It all goes to the inverted pyramid idea: matter accumulation is inverse in proportion with size and number. This is the golden rule that I don't have to scour the universe to prove its validity

  3. I wonder if we're the only ones in this universe, I don't believe so, there's got 2 be life of some sort on another Planet somewhere out there, I'll be searching the Sky at Night through my telescope until I find it, hopefully!!!!!!🤡👍🤣LOL

  4. Not a single shred of evidence to back the claims of Super-Earths, Mini-Neptune’s, Hot-Jupiter’s, etc. No proof of planet alignments close to their “Suns.” NASA is a GOVERNMENT agency who is only still relevant because most people refuse to ask questions, and use critical thinking skills. They simply believe what their rulers tell them and these lies get solidified by years of television PROGRAMMING. Thanks Hollywood, Disneyland, U.S. Miseducation System.
