It's a near vacuum. There is not enough matter to transfer a significant amount of heat to whatever object is passing through.
The amount of heat generated from friction is much more significant, and that's why ceramic shielding is a thing.
This is worth a listen. Not trying to convince you. It is worth listening to someone explain the other side of the argument. Someone sent me this video and it for the first time made me think critically. At minimal I agree it is possible we are being lied to. If you disagree that is ok but at least you have a better explanation by someone who can articulate it using compelling evidence.

Oh we are absolutely being lied to. This is just not one of those things.
You can observe the solar system from your back yard, and you can confirm that your observations align with the popular interpretation.
It's good people are skeptic and are exploring the world for themselves, but that doesn't change that these alternative views of the world are dated and don't hold up against the observations we are able to make with today's technology.
