Discoveries of the Solar System

Timeline created by sarsar
  • Keplar publishes first two laws of planetary motion

    Keplar publishes first two laws of planetary motion
    Law 1: The orbit of every planet is an ellipse with two foci.
    Law 2: A line joining a planet and the Sun sweeps out equal areas during equal intervals of time
  • Jupiter is discovered by Galileo

    Jupiter is discovered by Galileo
    Jupiter is the largest planet in our solar system. It is one-tenth the size of the sun and ten times the size of the earth.
  • Galileo discovers inertia

    Galileo discovers inertia
    Inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line. It is one of the properties that keep the planets in their orbits.
  • Callisto discovered by Marius

    Jupiter's moon, Callisto, was discovered by Galileo and Marius.
  • First telescope turned to space by Galileo

    In 1610, Galileo first turned a telescope to space, starting the scientific interest of space.
  • Io discovered by Galileo

  • Europa discovered by Galileo

  • Ganymede discovered by Galileo

  • Keplar publishes third law of planetary motion

    Keplar publishes third law of planetary motion
    Law 3: The square of the orbital period is directly proportional to the cube of the semi-major axis of its orbit.
  • Gravity discovered

    Gravity discovered
    Gravity was discovered by Sir Isaac Newton. Gravity is a key force that keeps the planets in orbit. While the Earth would "like" to move in a straight line, the sun's gravitational pull keeps the Panets in orbit.
  • Titan discovered by Huygens

    Titan discovered by Huygens
    Titan is the fifteenth and largest of Saturn's satellites.
  • Iapetus dicovered by Cassini

    Iapetus dicovered by Cassini

    Rhea dicovered by Cassini
    Rhea is the fourteenth and second largest of Saturn's moons
  • Dione discovered by Cassini

    Dione discovered by Cassini
    Dione is Saturn's twelfth satellite.

  • Sinope discovered by Nicholson

    Sinope is the furthest satellite from Jupiter.
  • Pluto discovered by Tombaugh

    Pluto discovered by Tombaugh
    Pluto was discovered by a complete accident. It was found while Clyde W. Tombaugh was searching the sky for Planet X. Instead of being called a planet, Pluto is considered to be a dwarf planet because of its size. Pluto has three moons, Charon, Hydra, and Nix. Pluto differs from the other planets by having the most irregular orbit. In some pionts in its orbit, Pluto is closer to the sun than Neptune. Its orbit is the furthest from circular.
  • Carme discovered by Nicholson

    Carme is Jupiter's fourteenth satellite.
  • Lysithea discovered by Nicholson

    Lysithea is the 11th of Jupiter's moons

  • Nereid discovered Kuiper

    Nereid discovered Kuiper
    Nereid is the furthest moon from Neptune.
  • Ananke discovered by Nicholson

    Ananke is Jupiter's 13th satellite.
  • Epimetheus discovered by Walker

    Epimetheus discovered by Walker
    Epimetheus is the fifth moon of Saturn. It is co-orbital.
  • Janus discovered by Audouin Dollfus

    Janus discovered by Audouin Dollfus
