What exoplanet has the highest Earth Similarity Index?
Currently, the highest rated planet on the ESI is KOI-4878.01, an unconfirmed exoplanet located about 1075 light years from Earth, which has a rating of 0.98.
Which exoplanet is most habitable?
K-type stars would provide the necessary conditions for super habitable exoplanets, which are exoplanets that could be more habitable than Earth. As of March 2020, only one potentially habitable exoplanet has been found orbiting a F-type star: Kepler-1632 b.
What is the closest known exoplanet to Earth?
Proxima Centauri b
The closest exoplanet found is Proxima Centauri b, which was confirmed in 2016 to orbit Proxima Centauri, the closest star to the Solar System (4.25 ly).
What is Kepler 22b ESI?
Kepler-22b is located 600 light-years away. While the planet is larger than Earth, its orbit of 290 days around a sun-like star resembles that of our world.
How is Kepler 438b similar to Earth?
Mass, radius and temperature Kepler-438b is an Earth-sized planet, an exoplanet that has a mass and radius close to that of Earth. It has a radius of 1.12 R 🜨, and an unknown mass. It has an equilibrium temperature of 276 K (3 °C; 37 °F), close to that of Earth.
Can we live on Kepler 1649c?
Based on its mass and radius, it is likely a terrestrial planet, though its proximity to its star means it may likely be tidally locked. Kepler-1649c is estimated to receive about three quarters of the amount of radiation from its host star as Earth does from the Sun….Kepler-1649c.

What is the biggest exoplanet?
List
| Exoplanet name | Radius ( R J) | Notes |
|---|---|---|
| HR 2562 b | 1.11 | Most massive planet with a mass of 30 M J, although according to most definitions of planet, it may be too massive to be a planet, and may be a brown dwarf instead. |
| Jupiter | 1 69,911 km | Largest planet in the Solar System, by radius and mass. Reported for reference |
Is there water on Proxima B?
The exoplanet is at a distance from its star that allows temperatures mild enough for liquid water to pool on its surface. Proxima b is a little more massive than the Earth and orbits in the habitable zone around Proxima Centauri, where the temperature is suitable for liquid water to exist on its surface.
How close is the nearest exoplanet?
35 light-years
Not only is COCONUTS-2b (named for the COol Companions ON Ultrawide orbiTS survey) the closest directly imaged exoplanet to Earth to date – at a distance of just 35 light-years – it’s a rarity among exoplanet discoveries: a relatively cool, massive gas giant, orbiting its star at a great distance.
Does Kepler 438b have a moon?
Orbit and possible moons Kepler-438b orbits its parent star once every 35 days and 5 hrs It is likely tidally locked due to its close distance to its star. A search for exomoons by the Hunt for Exomoons with Kepler project around Kepler-438b placed a maximum mass on a hypothetical moon at 29\% that of the planet.
What are the 5 most Earth-like exoplanets?
Meet The Five Most Earth-Like Exoplanets in The Universe (That We Know About) 1 1. Kepler 438b. Kepler 438b (ESI=0.88) has the highest ESI of any exoplanet known. Discovered in 2015 around a red dwarf star, significantly smaller 2 2. Gliese 667Cc. 3 3. Kepler 442b. 4 4. Kepler 62e & 62f. 5 5. Kepler 452b.
What is the largest exoplanet with the highest ESI?
Kepler 438b (ESI=0.88) has the highest ESI of any exoplanet known. Discovered in 2015 around a red dwarf star, significantly smaller and cooler than our sun, it has a radius only 12\% larger than Earth’s.
Which planets have the highest Earth Similarity Index?
Though differing in size and temperature, terrestrial planets of the Solar System tend to have high Earth Similarity Index values – Mercury (0.596), Venus (0.444), Earth (1.00) and Mars (0.697). Sizes to scale. The Earth Similarity Index (ESI) is a proposed characterization of how similar a planetary-mass object or natural satellite is to Earth.
What is the Earth Similarity Index (ESI)?
The Earth Similarity Index (ESI) is a proposed characterization of how similar a planetary-mass object or natural satellite is to Earth. It was designed to be a scale from zero to one, with Earth having a value of one; this is meant to simplify planet comparisons from large databases. The scale has no quantitative meaning for habitability.
