Question

I have 5 examples and I just need to know what Planet/Celestial bodyies they might come from.

Answer 1

1. The sample contains more than one element.
2. The sample seems to be radioactive.
3. The sample is estimated to have formed close to 4,600 million years ago.
4. The source can be found no more than 4.54 billion kilo meters from the sun.
5. The source was exposed to an atmosphere.---That's all

Answer 2

I think this is astrophysics, so it might be best to ask this in the physics section.

Answer 3

I posted it in all science-type sections, no answers.

Answer 4

Yeah, I don't know. What class are these questions for?

Answer 5

Just science 8th grade

Answer 6

well neptune is 4.5 billion kilometres from the sun...

that leaves us with

mercury, venus, earth, mars, jupiter, saturn and neptune..

all have atmospheres except mercury..

venus, earth, mars, jupiter, saturn and neptune

apparently gas giants (jupiter, saturn and neptune) are mainly composed of He and H, so no radioactive materials..

leaving us with: venus, earth, mars

so you have to take these into account, which i don't know much about:

1. The sample contains more than one element.
3. The sample is estimated to have formed close to 4,600 million years ago.
