# What did Uranium get its name from?

From the Greek $o u \rho \alpha \nu o s$............
And I think $o u \rho \alpha \nu o s$ means $\text{heaven}$.
As far as I know, uranium was first isolated by Martin Heinrich Klaproth in 1789 from the mineral pitchblende. Because the planet $\text{Uranus}$ had recently been discovered, he named the metal $\text{uranium} .$ Klaproth, apparently also isolated cerium, $Z = 58$, and zirconium, $Z = 40$; he must have been a very accomplished chemist - especially in the days before atomic number and mass had been properly elucidated.
