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 )
K2-33b (also known by its EPIC designation EPIC 205117205.01) is a very young super-Neptune exoplanet, orbiting the pre-main-sequence star K2-33.It was discovered by NASA's Kepler space telescope on its "Second Light" mission.
In 1970, millions of Americans concerned about the environment observed the first 'Earth Day.' Forty-four years later, the tradition and message of conserving our beautiful planet is still going ...

Kepler orbits the Sun, [59] [60] which avoids Earth occultations, stray light, and gravitational perturbations and torques inherent in an Earth orbit. NASA has characterized Kepler's orbit as "Earth-trailing". [61] With an orbital period of 372.5 days, Kepler is slowly falling farther behind Earth (about 16 million miles per annum). As of May 1 ...
The orbit lasts 4.4379637 days. Kepler-12b has an orbital inclination of 88.86º, indicating that the planet is seen as nearly edge-on with respect to the Earth and to its host star. [2] According to Kepler's official website, the mass and radius of the planet can be compared to 137 Earths (in mass) and 19 Earths (for its radius).
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]
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]
