Which planets in the solar system give off at least as much energy as they receive from the Sun?

Answer 1

Voodoid is right. The Jovian planets are also known as gas giants - gravity compresses the gasses so much that they reach temperatures of up to 20,000K in the case of Jupiter.

Answer 2

If, on average, they are not heating up, can not store energy, and do not have photosynthetic life - then all planets radiate at infra-red the same amount of energy as they receive from their Star.
So the answer is all of them, except possibly the earth.

If you take into account heat produced by radio-isotope decay within the planet then you might consider that they radiate more energy than they receive.
Io heats up as it is in an eccentric orbit about jupiter, giving rise to internal strains that heat the satellite. One would assume that if its temperature is more or less constant then it radiates more energy than it receives from the sun.

Answer 3

I would be surprised if any do. Energy can't be created, it can only be transferred, reflected, or changed to a different form of energy.

For any object to give off the same amount of energy that it receives, it would represent a 100% reflection and no absorption.

It's not possible to give off more than 100% unless the planet has it's own energy source.

Answer 4

The Jovian planets: Jupiter, Saturn, Uranus, and Neptune.

Answer 5

acceptable, in spite of the fact that if the vaccuum grew to grow to be throughout this planet, the only element is might do is larger acceptable than probable purely suck up rocks and meteors. by technique of our planet not being as super as diverse subject concerns, which means the g-forces wouldnt suck up something extensive. We dont emit heat temperature additionally, so we does not have the means to coach suited right into a black hollow. directly to the question. If the image voltaic will grow to be a crimson substantial, it wouldnt emit as a lot heat temperature, which means out planet and each and each of different planets will better acceptable than probable improve into ice planets. The image voltaic might get super. If it grew to grow to be suited right into a black hollow, it extremely is very almost not in all probability, it wouldnt be an distinctly super black hollow, by technique of our image voltaic not being as super simply by certainty the different diverse subject concerns interior the universe.((Our image voltaic purely being 12 image voltaic hundreds)) the only way it might desire to enhance suited right into a black hollow may be if it grew to grow to be to break down by technique of it not having sufficient gas to help its own heat temperature. which means it might might choose to coach suited right into a crimson substantial for over a million years, then improve right into a white dwarf, or a black hollow. simply by dimensions of our image voltaic, it wouldnt do very a lot, besides the certainty that it might suck up our planet and the close to to by technique of planets.

Answer 6

it`s venus if i`m not made a mistake..
probably because the structure of gases that surrounding its atmosphere..
