There is no atmosphere in space, which means that sound has no medium or way to travel to be heard.
THE HOTTEST PLANET IN OUR SOLAR SYSTEM IS 450° C.
Venus is the hottest planet in the solar system and has an average surface temperature of around 450° C. Did you know that Venus isn’t the closest planet to the sun? That is Mercury. You would think that Mercury would then be the hottest, but Mercury has no atmosphere (which regulates temperature), resulting in big fluctuations.
ONE MILLION EARTHS CAN FIT INSIDE THE SUN
The Sun is large enough that approximately 1.3 million Earths could fit inside (if squashed in) or if the Earths retained their spherical shape then 960,000 would fit.
