The degree to which an orbit deviates from a circle. The eccentricity of Earth’s orbit is 0.07.

Iridium The Iridium satellite constellation is a system of 66 active communication satellites and spares around the Earth. It allows worldwide voice and data communications using handheld devices. The Iridium network is unique in that it covers the whole earth, including poles, oceans and airways, however the service is interdicted due to American embargoes in North Korea, Iran, Libya and Sudan. The name was taken from the element Iridium, with the atomic number of 77 — the size of the satellite constellation projected in the early stages of planning.

Uranus With the exception of earth, all the other planets take their names from Roman myth. Uranus is the third-largest and fourth most massive planet in the Solar System. It is named after the ancient Greek deity of the sky. Sir William Herschel announced its discovery on March 13, 1781, expanding the known boundaries of the Solar System for the first time in modern history. Uranus was also the first planet discovered with a telescope.

It’s the distance within which a celestial body will disintegrate due to a second body’s tidal forces exceeding the first body’s gravitational self-attraction Inside the Roche limit, orbiting material will tend to disperse and form rings, while outside the limit, material will tend to coalesce. The term is named after Édouard Roche, the French astronomer who first calculated this theoretical limit in 1848

The number zero His Brahmasphutasiddhanta is the earliest known text to treat zero as a number in its own right. It goes well beyond that, however, stating rules for arithmetic on negative numbers and zero which are quite close to the modern understanding. The major divergence is that Brahmagupta attempted to define division by zero, which is left undefined in modern mathematics. His definition of zero was quite accurate except he wrongly believed that 0/0 was equal to 0
