Great! You already have some facts about the sun. Here are a few more facts:

8. The sun is about 4.6 billion years old.
To find this fact, you can refer to scientific research and studies that estimate the age of the sun based on various indicators such as its chemical composition, radiometric dating of meteorites, and computer models.

9. The sun's diameter is about 1.4 million kilometers.
You can find this fact by referring to scientific measurements and observations conducted by astronomers and space probes, such as the Solar and Heliospheric Observatory (SOHO) and the Solar Dynamics Observatory (SDO).

10. The sun rotates on its axis once every 24.47 days.
This information is obtained through observations of the surface of the sun and its different features, such as sunspots and solar prominences.

11. The temperature at the core of the sun is estimated to be around 15 million degrees Celsius.
To determine this fact, scientists study the behavior of particles, the energy emitted by the sun, and the nuclear fusion processes happening at its core.

12. The sun is a main-sequence star of spectral type G2V.
This fact is derived from the analysis of the sun's spectrum, which reveals its chemical composition and physical characteristics.

Remember, when looking for facts about the sun or any other topic, it's important to consult reliable sources such as scientific journals, textbooks, and reputable educational websites.
