Astronomical unit
The astronomical unit (symbol: au, or AU) is a unit of length defined to be exactly equal to.
See Kepler-20e and Astronomical unit
Day
A day is the time period of a full rotation of the Earth with respect to the Sun.
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life.
Exoplanet
An exoplanet or extrasolar planet is a planet outside the Solar System.
Kepler space telescope
The Kepler space telescope is a defunct space telescope launched by NASA in 2009 to discover Earth-sized planets orbiting other stars.
See Kepler-20e and Kepler space telescope
Kepler-20
Kepler-20 is a star about from Earth in the constellation Lyra with a system of at least five, and possibly six, known planets.
Kepler-20b
Kepler-20b is an exoplanet orbiting Kepler-20 in a system 922 light years from Earth. Kepler-20e and Kepler-20b are exoplanets discovered by the Kepler space telescope, exoplanets discovered in 2011, Kepler-20 and Transiting exoplanets.
Orbital eccentricity
In astrodynamics, the orbital eccentricity of an astronomical object is a dimensionless parameter that determines the amount by which its orbit around another body deviates from a perfect circle.
See Kepler-20e and Orbital eccentricity
Orbital inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body.
See Kepler-20e and Orbital inclination
Semi-major and semi-minor axes
In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the two most widely separated points of the perimeter.
See Kepler-20e and Semi-major and semi-minor axes
Solar analog
Solar-type stars, solar analogs (also analogues), and solar twins are stars that are particularly similar to the Sun.
See Kepler-20e and Solar analog
Solar System
The Solar SystemCapitalization of the name varies.
