To reach our sight, photons released from the Sun's surface must travel through the vacuum of space. How long does that take?
Answer 8 minutes and 20 seconds
Sunlight travels from the Sun's surface to the Earth in about 8.3 minutes. On the other hand, a photon traveling from the Sun's core to its surface would take between 10,000 and 170,000 years if it encountered a charged particle.
