Stars seem to be, but they don't have big and/or unstable atoms such as most radioactive elements have. They release sub atomic units when their atoms fuse, along with rays such as gamma rays, which is why they can seem to be similar to other radioactive things.
Some planets with atmostpheres that are ionised by ionising rays can also be similar to radioactive things perhaps.
What else can I help you with?
What three element symbols were named for planets?
None. Although Mercury, Uranium and Plutonium might seem to be named after planets they were not. They were named after ancient deities.
In what direction does the sun moon and stars move across the sky?
It is actually the Earth that moves, not the stars, but from the surface of the earth it appears that the stars are moving. Stars rise in the east and set in the west, rotating around an apparent "pole" formed by the North Staplus.

Do all planets have heavenly bodies?
oh yes, all the way, they are SO heavenly filled with bodies of the heavens, that even i cant stand the heavenliness! :0 Planets ARE heavenly bodies, as are stars. Some planets have satellites, and some don't.
Why is the imaginary sphere on which all objects in the sky seem to be located called the celestial sphere?
The imaginary sphere is called the celestial sphere because it provides a simplified model for understanding the positions and movements of celestial objects as they appear from Earth. By projecting the stars, planets, and other astronomical bodies onto this sphere, we can easily map their locations in the sky. This concept helps astronomers and navigators visualize the cosmos, despite the vast distances involved. The term "celestial" reflects its association with the heavens and the celestial bodies observed within it.
What do you call the imaginary dome of the sky to which the stars seem to be attached?
The imaginary dome of the sky to which the stars appear to be attached is called the celestial sphere. It is an imaginary sphere of infinite radius surrounding the Earth to which the stars and celestial bodies are fixed in our perception.
Why do planets seem brighter than stars?
Some planets seem brighter - not all of them. Planets are quite near to us, as compared to the stars.

The greek astronomers explanation for the celestial spheres did not encompass the phenomenon?
The Greek astronomer's explanation for the celestial spheres did not encompass the phenomenon of retrograde motion. The retrograde motion is the apparent motion of a planet to move in the opposite direction from the surrounding planetary bodies in the same system.

Were else can you find gravity but earth?
Yes. Gravity exists everywhere in the universe as all objects have a gravitational pull. Objects in space do not seem weightless because there is no gravity. Rather they seem weightless because they are in freefall.
Are all planets made of metal?
No, but they all seem to have metal cores. Minor planets are not so consistent.
