Uranus is the seventh planet from the sun and the first to be discovered by scientists. Although Uranus is visible to the naked eye, it was long mistaken as a star because of the planetâs dimness and slow orbit. The planet is also notable for its dramatic tilt, which causes its axis to point nearly directly at the sun. British astronomer William Herschel discovered Uranus accidentally on March 13, 1781, with his telescope while surveying all stars down to those about 10 times dimmer than can be seen by the naked eye.
Pluto has the least circular orbit of any of the planets in our Solar System. Pluto's orbit has an eccentricity of 0.2488. The Sun isn't quite at the center of a planet's elliptical orbit. An ellipse has a point a little bit away from the center called the focus.The Sun is at the focus of the ellipse. Because the Sun is at the focus, not the center, of the ellipse, the planet moves closer to and further away from the Sun every orbit.The close point in each orbit is called perihelion. The far away point is called aphelion.ecause the Sun is at the focus, not the center, of the ellipse, the planet moves closer to and further away from the Sun every orbit. The close point in each orbit is called perihelion. The far away point is called aphelion.
