What is an Astronomical Unit?
An Astronomical unit (usually abbreviated as “a.u.”) is a unit of measurement of measuring distances in the Solar System one a.u is equal to 149,597,870 km which is the mean or average distance between the earth and Sun during the elliptical orbit on the earth around the Sun.
Do the planets orbit the Sun in the same plane?
Except Pluto, the entire planet orbit the Sun nearly in the same plane. The plane of the orbit of Pluto is titled by about 170 to the mean plane of orbit of then other planets.
What is Bode’s Law (Titus-Bode Law)?
Bode’s Law, also known as Titus-Bode Law, relates to a unique empirical formula postulated by German astronomer J. Titus which apparently predicted the approximate distances of the then-known planets from the Sun in astronomical units.
The law correctly predicted the existence of Uranus and its distances from sun even before the planet Uranus was discovered. However, the law was rather off the mark in its prediction about Neptune and Pluto.
