Cerium, tellurium and uranium are named after heavenly bodies. Other elements that are named after heavenly bodies are helium, neptunium, plutonium and Mercury.
All bodies (heavenly and earthly) are affected by gravity stars, moons, planets, etc.
Heavenly bodies, by their very definition, are not "in the world" - they are in the heavens - that is, they are out of this world. Heavenly bodies include the Sun, the moon, the planets of the solar system and other stars and their planets. They are - literally - too many to count.
They are known as astronomers.
Neptunium and plutonium and uranium and titanium! Comment: There's more too, but they're not really named after the planets and heavenly bodies. It's just that the planets, etc and the elements are both named after the same things. I agree that historically there was a connection between the planets names and the naming of elements.
Multiple elements as listed by the Periodic Table of the Elements are named after bodies in the Cosmos. Helium (He) regards Greek Helios; the Sun. Mercury (Hg), Uranium (Ur), Neptunium (Np), and Plutonium (Pu) as in the planets, are others.
Uranium - Uranus Plutonium - Pluto Neptunium - Neptune and Titanium may be named after Titan?

Mercury the element is not really named after mercury the heavenly body: both are named after the Roman messenger god, Mercury. Similarly it is unclear whether uranium is named after uranus the planet or Uranus the mythical Roman god. Neptunium and plutonium definitely are named after the planets, and there is also selenium, named after the moon, and helium, named after the sun.
