  2. Kepler orbit - Wikipedia

    en.wikipedia.org/wiki/Kepler_orbit

    An elliptic Kepler orbit with an eccentricity of 0.7, a parabolic Kepler orbit and a hyperbolic Kepler orbit with an eccentricity of 1.3. The distance to the focal point is a function of the polar angle relative to the horizontal line as given by the equation ( 13 )

  3. Kepler-9b - Wikipedia

    en.wikipedia.org/wiki/Kepler-9b

    Kepler-9b's name denotes that it is the first exoplanet discovered in orbit around the star Kepler-9. The star, in turn, was named for the Kepler Mission, a NASA project designed to search for Earth-like planets. [5] Kepler-9's planets were among 700 planetary candidates collected during Kepler's first 43 days online.

  4. Orbital eccentricity - Wikipedia

    en.wikipedia.org/wiki/Orbital_eccentricity

    In a two-body problem with inverse-square-law force, every orbit is a Kepler orbit. The eccentricity of this Kepler orbit is a non-negative number that defines its shape. The eccentricity may take the following values: Circular orbit: e = 0; Elliptic orbit: 0 < e < 1; Parabolic trajectory: e = 1; Hyperbolic trajectory: e > 1; The eccentricity e ...

  6. K2-288Bb - Wikipedia

    en.wikipedia.org/wiki/K2-288Bb

    K2-288Bb is unusual for having a radius not commonly seen among most exoplanets. At 1.90 R 🜨, it falls within the so-called Fulton gap between 1.5 and 2.0 R 🜨.This is the range of sizes where rocky super-Earths start to accumulate thick volatile layers and turn into mini-Neptunes. [2]

  7. Parabolic trajectory - Wikipedia

    en.wikipedia.org/wiki/Parabolic_trajectory

    When moving away from the source it is called an escape orbit, otherwise a capture orbit. It is also sometimes referred to as a C 3 = 0 orbit (see Characteristic energy ). Under standard assumptions a body traveling along an escape orbit will coast along a parabolic trajectory to infinity, with velocity relative to the central body tending to ...

  8. Osculating orbit - Wikipedia

    en.wikipedia.org/wiki/Osculating_orbit

    Osculating orbit (inner, black) and perturbed orbit (red) In astronomy, and in particular in astrodynamics, the osculating orbit of an object in space at a given moment in time is the gravitational Kepler orbit (i.e. an elliptic or other conic one) that it would have around its central body if perturbations were absent. [1]

  9. Kepler-8 - Wikipedia

    en.wikipedia.org/wiki/Kepler-8

    Kepler-8 was named the way it was because it is home to the eighth planetary system confirmed during the course of the Kepler Mission, a NASA-directed program tasked with searching a region of the sky for terrestrial planets that transit, or cross in front of (and thereby, for a while, make dimmer) the stars that they orbit with respect to Earth.
