Why are there no stars in the pictures of Earth?
Why can’t we see stars in the pictures of spacewalking or moonwalking astronauts? The stars aren’t visible because they are too faint. The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures.
What does Earth look like from space today?

How big is the Earth compared to other planets?
The Size Of Earth Compared to Other Planets and Stars (and the Universe) With a radius that is approximately 883 times that of the Sun, it is one of largest stars, if placed in the center of the Solar System, its outer surface would lie between the orbits of Mars and Jupiter.
How big is the Sun compared to other stars?
Since the Sun is the best-known star for us, solar radius and solar mass are two useful units of measurement to depict how big is a star. A solar radius is approximately 690,000 km (432,000 miles) and 1 solar mass is 2 x 10 30 kilograms (4.3 x 10 30 pounds). With a radius of 1,708 ± 192 Solar Radii, UY Scuti is probably the biggest known star.
