Fire is a chemical reaction which requires significant quantities of atmospheric oxygen (and also heat, and fuel). In our solar system, Earth would be the only planet capable of sustaining fire in its familiar form, but even so, fuel would be so limited that one could not fairly characterize that the planet itself would be "set on fire."
Sometimes the Sun is notionally considered to be like fire, or "burning", but the nuclear fusion processes underway in its core have a much higher characteristic energy than the chemical reactions of fire, so it remains only a metaphor.
A planet could not be made of fire, but there are probably planets in the universe that are entirely covered in lava. These would usually be very young planets.
We can set foot on all the planets in the solar system including the terrestrial planets, except for gas giants, which are Jupiter and Saturn. We can't set foot on Jupiter and Saturn because there's no solid surface and it's so gaseous. Uranus and Neptune are also a gas giant but they're considered an ice giant, so there's a solid surface in these 2 ice giants. We can set foot in all planets except for Jupiter and Saturn.
Heliocentrism is the "truth" discovered by Galileo that is depicted burning in the fire with him. Heliocentrism is the idea that Earth and the other planets in our galaxy revolve around the Sun. The fire in the picture represents the sun, with the surrounding people representing the planets and the Earth's moon. Hope this helped!
Yes, grass can be set on fire if exposed to a flame or sufficient heat source. Dry grass is more flammable than wet grass. It is important to exercise caution when setting grass on fire, as fires can quickly spread out of control.
Well, typically there are no trees in a desert, so you just call it a fire. no special name.

A combustible material can be set on fire. You can also set a frying pan on (a) fire.
gas planets
I would say ice is not easily set on fire.
An iPod will not catch fire by itself, but you can set an iPod on fire.
Set the Fire was created in 1984.
Hydrogen does not set things on fire. Hydrogen itself is flammable and can be set on fire by a spark or flame.
Set Yourself on Fire was created in 2003.
