But can you visualise that number of Earths?Ħ. 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. ONE MILLION EARTHS CAN FIT INSIDE THE SUN If the Sun had a voice would it be high and squeaky from all that helium?ĥ. Did you know that the Sun is made up of mostly hydrogen (three quarters worth) with the rest of its mass attributed to helium.
