    Mars-crossing minor planets; Asteroids in the asteroid belt, between the orbits of Mars and Jupiter Ceres, a dwarf planet; Pallas; Vesta; Hygiea; Asteroids number in the hundreds of thousands. For longer lists, see list of exceptional asteroids, list of asteroids, or list of Solar System objects by size. Asteroid moons

  3. Kepler orrery - Wikipedia

    en.wikipedia.org/wiki/Kepler_orrery

    The Kepler orrery is a group of animations created by Daniel Fabrycky and Ethan Kruse, which show exoplanets and stars discovered by the Kepler Space Telescope. 1,815 exoplanets and 726 planetary systems are in the animation. [1] The sizes of the planet orbits are to scale with each other, including the orbits of the planets in the local solar ...

  4. List of orbits - Wikipedia

    en.wikipedia.org/wiki/List_of_orbits

    In the Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris. Moons by contrast are not in a heliocentric orbit but rather orbit their parent object. Geocentric orbit: An orbit around the planet Earth, such as that of the Moon or of artificial satellites.

  5. Solar System - Wikipedia

    en.wikipedia.org/wiki/Solar_System

    Animations of the Solar System's inner planets orbiting. Each frame represents 2 days of motion. Animations of the Solar System's outer planets orbiting. This animation is 100 times faster than the inner planet animation. The planets and other large objects in orbit around the Sun lie near the plane of Earth's orbit, known as the ecliptic ...

  6. Orbit - Wikipedia

    en.wikipedia.org/wiki/Orbit

    An animation showing a low eccentricity orbit (near-circle, in red), and a high eccentricity orbit (ellipse, in purple). In celestial mechanics, an orbit (also known as orbital revolution) is the curved trajectory of an object [1] such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such ...

  7. Orrery - Wikipedia

    en.wikipedia.org/wiki/Orrery

    It displays the planets across the width of a room's ceiling, and has been in operation almost continually since it was created. [21] This orrery is a planetarium in both senses of the word: a complex machine showing planetary orbits, and a theatre for depicting the planets' movement.

  8. Kepler's laws of planetary motion - Wikipedia

    en.wikipedia.org/wiki/Kepler's_laws_of_planetary...

    A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. The square of a planet's orbital period is proportional to the cube of the length of the semi-major axis of its orbit. The elliptical orbits of planets were indicated by calculations of the orbit of Mars.

  9. Orbital eccentricity - Wikipedia

    en.wikipedia.org/wiki/Orbital_eccentricity

    The table lists the values for all planets and dwarf planets, and selected asteroids, comets, and moons. Mercury has the greatest orbital eccentricity of any planet in the Solar System (e = 0.2056), followed by Mars of 0.093 4. Such eccentricity is sufficient for Mercury to receive twice as much solar irradiation at perihelion compared to aphelion.
