You're asking about planets that do not emit more radiation than they receive from the sun. This means we're looking for planets that are not hotter than they should be based solely on the sunlight they absorb.

Here's why:

* Planets radiate energy based on their temperature. The hotter a planet, the more radiation it emits.

* The Sun is the primary source of heat for planets in our solar system. Planets absorb sunlight and this energy warms them up.

* Some planets are hotter than expected due to internal heat sources. For example, Jupiter emits more radiation than it receives because of its internal heat generated from gravitational pressure.

Now, let's look at the common planets:

* Venus: Has a runaway greenhouse effect, making it incredibly hot and emitting far more radiation than it receives.

* Earth: Has a balanced energy budget, generally emitting roughly the same amount of radiation as it receives (though this is changing due to human activity).

* Mars: Is a cold planet and emits less radiation than it receives.

* Jupiter: Emits more radiation than it receives due to internal heat sources.

* Saturn: Emits more radiation than it receives due to internal heat sources.

Therefore, the two planets that do not emit more radiation than they receive from the Sun are:

1. Earth

2. Mars
