  2. Habitable zone - Wikipedia

    en.wikipedia.org/wiki/Habitable_zone

    Proxima Centauri b, located about 4.2 light-years (1.3 parsecs) from Earth in the constellation of Centaurus, is the nearest known exoplanet, and is orbiting in the habitable zone of its star. [13] The HZ is also of particular interest to the emerging field of habitability of natural satellites , because planetary-mass moons in the HZ might ...

  3. Near-Earth supernova - Wikipedia

    en.wikipedia.org/wiki/Near-Earth_supernova

    The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs (pc) [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.

  4. LHS 1140 - Wikipedia

    en.wikipedia.org/wiki/LHS_1140

    The planet LHS 1140 b is a super-Earth in the habitable zone and transits the star every 24.7 days. This should allow its atmosphere to be studied in future: the combination of the transiting super-Earth and the relatively small and nearby host star make this system one of the most promising known for atmosphere studies, along with the TRAPPIST ...

    K2-18b, also known as EPIC 201912552 b, is an exoplanet orbiting the red dwarf K2-18, located 124 light-years (38 pc) away from Earth.The planet is a sub-Neptune about 2.6 times the radius of Earth, with a 33-day orbit within the star's habitable zone.

  6. Kepler-452b - Wikipedia

    en.wikipedia.org/wiki/Kepler-452b

    Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.

  7. Galactic anticenter - Wikipedia

    en.wikipedia.org/wiki/Galactic_anticenter

    The galactic anticenter is a direction in space directly opposite to the Galactic Center, as viewed from Earth. This direction corresponds to a point on the celestial sphere . From the perspective of an observer on Earth, the galactic anticenter is located in the constellation Auriga , and the Crab nebula and the bright star Beta Tauri (Elnath ...

  8. TRAPPIST-1f - Wikipedia

    en.wikipedia.org/wiki/TRAPPIST-1f

    TRAPPIST-1f, also designated as 2MASS J23062928-0502285 f, is an exoplanet, likely rocky, [2] orbiting within the habitable zone [5] around the ultracool dwarf star TRAPPIST-1, located 40.7 light-years (12.5 parsecs) away from Earth in the constellation of Aquarius.

  9. Kepler-22b - Wikipedia

    en.wikipedia.org/wiki/Kepler-22b

    It was discovered by NASA's Kepler Space Telescope in December 2011 and was the first known transiting planet to orbit within the habitable zone of a Sun-like star, where liquid water could exist on the planet's surface. [4] Kepler-22 is too dim to be seen with the naked eye. Kepler-22b's radius is roughly twice that of Earth. [5]
