Exploring the TRAPPIST-1 System
We've briefly discussed exoplanets and some methods that we can use to detect them, but we haven't yet looked at any specific ones. You may have heard of the TRAPPIST-1 system that was discovered recently, and for good reason, it's a very exciting discovery! Let's get a closer look at this system on Space Engine and see just what makes it so special.

Are the TRAPPIST-1 Planets Home to Life?
With a record number of exoplanets in this star’s habitable zone, the TRAPPIST-1 system is a likely contender for biological life beyond our solar system. Watch More Space Crafts! | https://bit.ly/2w0YKD1 Read More:
TRAPPIST-1 | About
“The TRAPPIST-1 worlds are the most optimal currently at our disposal. They are providing humanity with its first opportunities at discovering evidence of biology beyond the Solar system.” TRAPPIST-1 Planets Are Even More Like Earth Than We Thought
“The TRAPPIST-1 system is made up of seven roughly Earth-sized planets orbiting a dwarf star around 39 light-years away and is often hailed as the most likely place for life outside our solar system that we know of. A new study offers further insight into each TRAPPIST planet's biological properties and the signs are encouraging.” New Clues to TRAPPIST-1 Planet Compositions, Atmospheres
“In the year since NASA announced the seven Earth-sized planets of the TRAPPIST-1 system, scientists have been working hard to better understand these enticing worlds just 40 light-years away.” ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

Predicting the Orbit of TRAPPIST-1i
TRAPPIST-1 is an amazing system discovered last year featuring seven roughly Earth-sized planets all transiting their diminutive parent star. Could there be an eighth? If there is, in this video Prof Kipping argues that it should be possible to precisely predict what the orbital period of such a planet would be. Right or wrong, this prediction provides a falsifiable hypothesis to test our understanding of the rules governing planetary system architectures. ► Kipping (2018), "Predicting the Orbit of TRAPPIST-1i", AAS research note: https://arxiv.org/abs/1807.10835

The Ultracool TRAPPIST-1 System: 7 Terrestrial Worlds, 7 Chances for Ice and Life
Planetary scientist Dr. Susan Lederer of the Astromaterials Research and Exploration Science (ARES) Division at the NASA’s Johnson Space Center discusses the discovery of the TRAPPIST-1 extrasolar system. Lederer also discusses the potential habitability of the seven planets orbiting the parent star. This was the fifth and final presentation in the Lunar and Planetary Institute’s 2017–2018 Cosmic Exploration Speaker Series, “Diving into Ocean Worlds.”
Standing on Trappist-1 Planets
My twitter: https://twitter.com/Dreksler_Astral
Trappist-1 is a system with seven planets, out of them three are in the habitable zone, but that does not mean they are habitable. Still i take a look at what would it be like to stand on them and i explore the topic a bit. Intro, outro and other clips in the video were made with Space Engine. Images are by NASA.

Homes Away From Home? Revisiting the Seven Planets of TRAPPIST-1
One year ago, astronomers announced the discovery that seven roughly Earth-sized worlds orbited around the nearby star TRAPPIST-1. Now a year later, additional data have refined our understanding of these planets.We now know more about the TRAPPIST-1 system than any other solar system other than our own.
Imagining the Planets of TRAPPIST-1
This video shows artist's concepts of the seven Earth-sized planets of TRAPPIST-1, an exoplanet system about 40 light-years away, based on data current as of February 2018. Each planet is shown in sequence, starting with the innermost TRAPPIST-1 b and ending with the outermost TRAPPIST-1 h. The video presents the planets’ relative sizes as well as the relative scale of the central star as seen from each planet. The art highlights possibilities for how the surfaces of these intriguing worlds might look based on their newly-calculated properties. The seven planets of TRAPPIST-1 are all Earth-sized and terrestrial. TRAPPIST-1 is an ultra-cool dwarf star in the constellation Aquarius, and its planets orbit very close to it. In the background, slightly distorted versions our familiar constellations, including Orion and Taurus, are shown as they would appear from the location of TRAPPIST-1 (backdrop image courtesy California Academy of Sciences/Dan Tell).
Hubble Probes Exoplanet Atmospheres in TRAPPIST-1 Habitable Zone
Worlds in the Star’s Habitable Zone Are Not Smothered Under Primordial Atmospheres Only 40 light-years away — a stone’s throw on the scale of our galaxy — several Earth-sized planets orbit the red dwarf star TRAPPIST-1. Four of the planets lie in the star’s habitable zone, a region at a distance from the star where liquid water, the key to life as we know it, could exist on the planets’ surfaces. Astronomers using NASA's Hubble Space Telescope have conducted the first spectroscopic survey of these worlds. Hubble reveals that at least three of the exoplanets do not seem to contain puffy, hydrogen-rich atmospheres similar to gaseous planets such as Neptune. This means the atmospheres may be more shallow and rich in heavier gases like those found in Earth’s atmosphere, such as carbon dioxide, methane, and oxygen. Astronomers plan to use NASA’s James Webb Space Telescope, scheduled to launch in 2019, to probe deeper into the planetary atmospheres to search for the presence of such elements that could offer hints of whether these far-flung worlds are habitable. Artist's Concept: NASA and JPL/Caltech
Exoplanets Around TRAPPIST-1 Probably Rich in Water
A new study has found that the seven planets orbiting the nearby ultra-cool dwarf star TRAPPIST-1 are all made mostly of rock, and some could potentially hold more water than Earth. The planets' densities, now known much more precisely than before, suggest that some of them could have up to 5 percent of their mass in the form of water — about 250 times more than Earth's oceans. This ESOcast takes a quick look at this important result. Credit: ESO Editing: Nico Bartmann.

Size Comparison: The Seven Exoplanets of TRAPPIST-1
This artist’s impression video compares the seven planets orbiting the ultra-cool red dwarf star TRAPPIST-1 at the same scale. New observations, when combined with very sophisticated analysis, have now yielded good estimates of the densities of all seven of the Earth-sized planets and suggest that they are rich in volatile materials, probably water. They are shown to the same scale but not in the correct relative positions. Credit: ESO/M. Kornmesser

TRAPPIST-1 Planets May Harbor Substantial Amounts of Water
A study of ultraviolet radiation emitted by the TRAPPIST-1 star reveals that the outer planets may have water on their surfaces, including 3 Earth-sized planets in the habitable zone of the system. -- How long would it take to get there on Space.com: https://www.space.com/35796-trappist-1-alien-planets-travel-time.html Credit: Space.com / animations courtesy: ESO/L.

Animation of the planets orbiting TRAPPIST-1
This animation shows all seven planets orbiting the ultracool dwarf TRAPPIST-1. The constellation of Orion (The Hunter) is visible below the star although it looks slightly different from how it appears from Earth because it is seen from a different star system. The artist’s impression in this video is based on the known physical parameters for the planets and stars seen, and uses a vast database of objects in the Universe.

A Resonant Dance of the Seven TRAPPIST-1 Planets
The animation shows a simulation of the planets of TRAPPIST-1 orbiting for 90 Earth-days. After 15 Earth-days, the animation focuses only on the outer three planets: TRAPPIST-1f, TRAPPIST-1g, TRAPPIST-1h. The motion freezes each time two adjacent planets pass each other; an arrow appears pointing to the location of the third planet. This complex but predictable pattern, called an orbital resonance, occurs when planets exert a regular, periodic gravitational tug on each other as they orbit their star. The three-body resonance of the outer three planets causes the planets to repeat the same relative positions, and expecting such a resonance was used to predict the orbital period of TRAPPIST-1h.
