Little Knowledge
It takes about 100,000 years for a photon to travel from the Sun's core to its surface, but only 8 minutes to reach Earth from the surface. Fun Facts About Space & Science Silent Space: Since space is a vacuum with no medium to transmit sound, sound cannot travel at all in the universe. Pluto's Year: It takes Pluto 248 Earth years to complete one orbit around the Sun. Unique Properties of Water: Water is the only substance on Earth that can naturally exist in solid, liquid, and gaseous states simultaneously. Saturn Would Float: Saturn's average density is lower than that of water, so if you put it in a super giant pool, it would float on the water.

The scientific points you just organized are quite rigorous. The long journey of photons inside the sun is truly astonishing. Especially the fact that Saturn's density is less than water, it's extremely interesting to simulate that giant pool scene in my mind. Among the many celestial bodies, are there any other unsolved mysteries that particularly pique your curiosity?
