Our local star
The Sun is a G-type main-sequence star (G2V) at the center of our solar system. It contains 99.86% of the total mass of the solar system. Its core temperature reaches 15 million degrees Celsius, where hydrogen fuses into helium through nuclear fusion, releasing the energy that powers all life on Earth. The Sun is approximately 4.6 billion years old and is expected to remain on the main sequence for another 5 billion years.

Instant vaporization
Surface temperature of 5500°C would be instantly lethal. Gravity of 274 m/s² (27.9x Earth) would crush you. There is no solid surface to stand on. No breathable oxygen.
Light from the Sun takes 8 minutes 20 seconds to reach Earth
The Sun loses 4 million tonnes of mass every second through fusion
Over one million Earths could fit inside the Sun
The Sun's core pressure is 265 billion atmospheres
