In general, you can expect to receive around 6,000 photons of starlight per second per square centimeter of your skin. This may not seem like much, but it's enough to allow you to see stars under ideal conditions.
The number of photons you receive will vary depending on your location on Earth. If you are located near the equator, you will receive more starlight than if you are located near the poles. This is because the Earth's curvature blocks some of the starlight from reaching the poles.
The time of day or night will also affect the amount of starlight you receive. You will receive the most starlight at night, when the Sun is not shining. During the day, the Sun's light will overpower the starlight, making it more difficult to see the stars.
Finally, the weather conditions will also affect the amount of starlight you receive. Clouds and precipitation can block some of the starlight from reaching the Earth's surface. On a clear night, you will be able to see more stars than on a cloudy night.
Despite all of these factors, you can still expect to receive a significant amount of starlight on Earth. Starlight is a reminder that we are part of a vast universe, and that there are many more stars out there than we can ever see with our naked eyes.
