Kepler-452b - Wikipedi

  1. The host star, Kepler-452, is a G-type and has about the same mass as the sun, only 3.7% more massive and 11% larger. It has a surface temperature of 5757 K, nearly the same as the Sun, which has a surface temperature of 5778 K
  2. Kepler 452b is located around 1,400 light years from Earth in the constellation of Cygnus. It is the smallest planet yet discovered that orbits in the habitable zone around a sun-like star. The habitable zone, also known as the 'Goldilocks Zone', is an area around a star which has just the right temperature to allow for liquid water to exist
  3. Both planets orbit a G2-type star of about the same temperature; however, the star hosting Kepler-452b is 6 billion years old, 1.5 billion years older than our sun. As stars age, they become larger, hotter and brighter, as represented in the illustration. Kepler-452b's star appears a bit larger and brighter

Kepler 452b is possibly the right temperature to allow liquid water to exist on the surface — as far as we know, this is essential for supporting life. According to John Coughlin, a researcher at the SETI Institute in California, the Kepler team worked with geologists to find out the make-up of the planet

If Kepler-452b nevertheless has a similar composition to Earth, we run into another problem: gravity. Based on an Earth-like density, Kepler-452b would be five times more massive than our planet ♦ While Kepler-452b is larger than Earth, its 385-day orbit is only 5 percent longer. ♦ The planet is 5 percent farther from its parent star Kepler-452 than Earth is from the Sun. ♦ Kepler-452 is 6 billion years old, 1.5 billion years older than our sun, has the same temperature, and is 20 percent brighter and has a diameter 10 percent.

I t is not known if Kepler-452b is a rocky planet but based on its small radius, Kepler-452b is likely rocky. It is not clear if Kepler-452b offers habitable environments. It orbits a G2V-type star, like the Sun, with nearly the same temperature and mass and 20% more luminous. However, the star is six billion years old, making it 1.4 billion years older than the Sun Abstract: Kepler-452b is currently the best example of an Earth-size planet in the habitable zone of a sun-like star, a type of planet whose number of detections is expected to increase in the future. Searching for biosignatures in the supposedly thin atmospheres of these planets is a challenging goal that requires a careful selection of the targets Não se sabe ao certo se Kepler-452b é um planeta rochoso ou um planeta gasoso pequeno, mas com base em seu pequeno raio, Kepler-452b tem uma chance razoável de ser rochoso. Não está claro se Kepler-452b oferece ambientes habitáveis. Ele orbita uma estrela do tipo G2V, como o Sol, com quase a mesma temperatura e massa According to Jenkins et al., Kepler 452b is in a 384.84-day orbit with an average orbital radius of Kepler 452b is 1.046 +0.019/-0.015 AU. This orbital radius is far outside that where a planet would become tidally locked and be affected by severe stellar flare activity - two unresolved issues that call into question the potential.

Kepler-452b. Es un exoplaneta que gira en la orbita de una estrella amarilla, parecida a nuestro sol, bautizada cono Kepler 452, de casi igual temperatura pero de un 20% de más brillo.El Kepler-452b fue descubierto en julio de 2015 por el telescopio kepler.Se encuentra a 1400 millones de años-luz y su tamaño es +60% de la Tierra.Por sus. If Kepler 452b has a 'base' temperature of 265 K. , the presence of an Earth-like atmosphere would presumably raise this to somewhat above the current average temperature of Earth. Since the Kepler planet has a mass several times that of Earth, it seems probable that it retains a thicker atmosphere These factors result in an estimated equilibrium temperature (Teq) of 265 K for Kepler-452b. This is a little hotter than Earth, which has Teq of 255 K and a mean surface temperature of 288 K. Kepler-452 is also the most metallic star in Table 1, raising the chances that it might harbor one or more gas giants in addition to its single confirmed.
