The angular size of the Sun is about 0.5 degrees as viewed from Earth. This means the Sun's apparent diameter is approximately half a degree in the sky, making it similar in size to the Moon when observed from our planet.

FAQs & Answers

  1. What is the angular size of the Moon? The angular size of the Moon is also about 0.5 degrees, making it appear similar in size to the Sun from Earth.
  2. How is angular size measured? Angular size is measured in degrees and represents how large an object appears from a specific point of view.
  3. Does the Sun's size change during the year? No, the angular size of the Sun remains roughly constant but can slightly vary due to Earth's elliptical orbit.
  4. Why do solar eclipses occur? Solar eclipses occur when the Moon passes directly between the Sun and Earth, blocking the Sun's light temporarily.
