The sun's brightness when measured from Earth is approximately 100,000 lux on a clear day.
The sun emits about 100,000 lux of light on a clear day.
Distances between stars and Earth are measured using a method called parallax. This involves observing the apparent shift in position of a star when viewed from different points in Earth's orbit around the Sun. By measuring this shift, astronomers can calculate the distance to the star.
No, the sun does not orbit Earth. Earth orbits around the sun.
Yes, the Earth orbits the Sun.
No, the Earth orbits around the Sun.

light years.
The sun emits about 100,000 lux of light on a clear day.
No dependency, when measured on Earth.
1 astronomical unit.
Bigger objects like celestial bodies ,Earth ,sun their radius are measured in kilometers .
I think you mean the distance from the Earth to the Sun. This distance is measured in Astronomical Units (AU)
a year.
I believe approximately 1 UA
Because it only takes 8 minutes for sunlight to reach Earth, but it takes 4 hours to reach Neptune.
Eratosthenes measured the size of Earth by using the Sun's angles, as well as a bit of geometry.
That has already been closely watched and carefully measured, bymany skilled and dedicated astronomers. It takes 687 earth days.
