They circle tightly around a dim dwarf star called Trappist-1, barely the size of Jupiter. Three planets are in the so-called habitable zone, where water and, possibly life, might exist. The others are right on the doorstep.Scientists say they need to study the atmospheres before determining whether these planets could support some type of life.Last spring, the University of Liege's Michael Gillon (GEE-yon) reported finding three planets around Trappist-1. Now the count is up to seven, and Gillon says there could be more.NASA - COURTESY NASAWashington, DC - 22 February 20171. NASA animation of revolving planet in TRAPPIST-1 (solar) System2. SOUNDBITE (English):Thomas Zurbuchen, Associate Administrator, Science Mission Directorate, NASA  +++PARTIALLY COVERED WITH NASA GRAPHIC+++\"I'm excited to announce today that Dr. Michael Gillon and his team have used our Spitzer Space Telescope to determine that there are seven earth-size planets orbiting the nearby TRAPPIST-1 star about 40 light-years away. What's more, as you can see in this illustration is that three of these planets marked in green are in the habitable zone where liquid water can pool on the surface. In fact, with the right atmospheric conditions, there could be water on any of these planets. So for the first time we have found as many terrestrial planets around a single star and that's the first time we've been able to measure that. In addition to that both the masses, and the radii of these habitable-zone earth-size planets.3.

SOUNDBITE (English):Sean Carey, Manager, NASA'S Spitzer Science Center Caltech/IPAC (IPAC is Infrared Processing and Analysis Center) \"In my opinion, this is the most exciting discovery we've had yet with Spitzer and it's almost 14 years of operation. As you can see in the graphic, the initial discover of the Trappist-1 System, was by the Trappist Telescope in Chile in 2016. Immediately after that we started doing intensive follow-up with a lot of ground-based telescopes in more than 20 days of continuous observation with Spitzer, and what we're able to find is that we were able to confirm two of the planets were found in the initial discovery and then found five more planets for a total of 7 planets in the system, which is pretty exciting.\"  5.

We'll in our case the basketball would be the sun, and the golf ball would be TRAPPIST-1 is much cooler, much smaller than our sun, and so the planets in its habitable zone are much closer to it, very close to it with very short orbital periods and in this graphics, what you can see are the planets, which are found around Trappist-1 with the three of them in the habitable, or so-called the \"Goldilocks Zone\" where liquid water could exist is most likely to exist at the surface of the rocky planet.\"8.
