Planets change orbit shape around Neptune’s size. Metal-rich stars help giant planets form. Eccentric orbits suggest chaotic planet formation.

Keep your eye on the ball” is a motto for many athletes—and for astronomers trying to find Earth-threatening space rocks ...

The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star.

It was not until Johannes Kepler introduced the concept of elliptical orbits that scientists ... exoplanets within the highly eccentric orbit group had 25% more habitable land area for more ...

Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have very elliptical orbits ... data collected by NASA’s Kepler telescope, which monitored ...

How does a planet’s size influence its orbit around its parent star? This is what a recent study published in the Proceedings of the National Academy | Space ...

To see this, recall the definition of angular momentum: Kepler's second law states that the area swept out by the line connecting the satellite to the Earth's center over a given time Δt is a constant ...

Concepts of orbital motion such as Kepler Laws, Elliptic, Parabolic and Hyperbolic orbits are introduced. Hohmann orbit transfer, ground station visibility, launch windows are explained. The module ...
