Kepler orbit led to Johannes Kepler working on his celestial mechanics. He later became known as the father of calculus. In 1601, Johannes Kepler acquired the extensive, meticulous observations of the planets made by Tycho Brahe. Kepler would spend the next five years trying to fit the observations of the planet Mars to various curves. In 1609, Kepler published the first two of his three laws of planetary motion. The first law states: More generally, the path of an object undergoing Keplerian motion may also follow a parabola or a hyperbola, which, along with ellipses, belong to a group of curves known
Virtual Planetary Laboratory explore the distribution of habitable worlds in the universe. The VPL team studies the effects of galactic, stellar, and planetary environments on planetary habitability. Task D incorporates VPL researchers from diverse and interdisciplinary fields who use laboratory work combined with chemical and climate models to study the impact of life on its environment. In addition, the interactions between the biosphere, planet, and host star are explored to determine how they can influence detectable biosignatures. In the final task, the VPL scientists observe our Solar System and extrasolar planets. The goal of this task is to develop astronomical and remote-sensing retrieval
