Sun is a mythic star. It has spectral type G2V.
A photon made in the core ricochets for tens of thousands of years before it reaches the surface — then crosses to Earth in eight minutes.

Trivia
Hard to believe
- Fuel burn. It converts about 4 million tonnes of its own mass into pure energy every second, and has done so for 4.6 billion years.
What it actually is
- The slow way out. A photon made in the core ricochets for tens of thousands of years before it reaches the surface — then crosses to Earth in eight minutes.
- Spectral class. Classed G2V — a perfectly ordinary yellow dwarf, brighter than about 85% of the stars in the galaxy but nothing remarkable.
Sense of scale
- How big. About 1.3 million Earths would fit inside it, and it holds 99.86% of all the mass in the Solar System.
Time and light
- Sunlight is old news. Light takes 8 minutes 20 seconds to reach Earth — so you never see the Sun as it is, only as it was.
By the numbers
- Two temperatures. Its surface is about 5,500°C, but the core where fusion actually happens runs at roughly 15 million°C.
- Its radius. Its radius is about 696 thousand km, roughly 109 times Earth's.
What's in a name
- Named. Notable enough to have earned a proper name, not just a catalogue number.

How to see it
Like any astronomical target, Sun is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. Because it moves against the background stars, the live position panel on this page tracks where it is right now. The visibility panel above works out tonight's viewing window for your saved location.
Why Sun is a mythic star
Sun scores 151 points on Spacedle's rarity scale, which places it in the mythic tier.
That score comes from 5 science badges — Star, Has a proper name, Our Sun, Sun-like G-type star and Main-sequence star — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
