FAQ
Q: What is the diameter of the Sun?
A: The diameter of the Sun is about 1.4 million kilometers.
Q: How does the diameter of the Sun compare to the Earth?
A: The diameter of the Sun is approximately 109 times that of the Earth.
Q: What is nuclear fusion?
A: Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
Q: What is the Photosphere of the Sun?
A: The Photosphere is the visible outer layer of the Sun made of gas and photons, representing the sun's visible edge.
Q: What is the difference between the Earth's spheroid shape and the Sun's oblate spheroid shape?
A: The Earth is an oblate spheroid due to its rotation, being slightly flattened at the poles and bulging at the equator, while the Sun is an oblate spheroid due to its rapid rotation.
Q: What is the Sun's corona?
A: The corona is the outermost layer of the Sun's atmosphere that extends into space, visible during a total solar eclipse as a faint halo.
Q: What is the magnetosphere of the Sun?
A: The magnetosphere of the Sun is the region around it where the motion of charged particles is affected by the Sun's magnetic field.
Q: Can multiple Earths fit within the volume of the Sun?
A: Yes, multiple Earths can fit within the volume of the Sun, approximately 1.3 million Earths could fit inside it.
Q: What are sunspots?
A: Sunspots are temporary dark spots on the Sun's surface caused by intense magnetic activity, slightly cooler than the surrounding areas.
