Does the sun create or reflect light?

The sun emits light, which means the electrons in its atoms have so much energy that they rise and fall in the electron cloud giving off light. The moon reflects, light meaning that the source didn’t generate the light; light from another source just bounced off of its surface.

Do asteroids reflect sunlight?

Asteroids do not shine like a steady beacon with constant brightness. They instead reflect a varying amount of sunlight toward the Earth. The observed brightness variation, also known as a light curve, is periodic, often with two maxima and two minima.

Why does the moon reflect light?

The moon shines because its surface reflects light from the sun. At any given point in the moon’s trajectory around the Earth, only half of its surface is facing the sun, and therefore, only half of the moon is lit up. The other half of the surface faces away from the sun and is in shadow.

Why Sun is white on Mars?

When you look at the Martian sunset, you actually see that “the disk of the sun is white, because light doesn’t change color as it passes through the Martian atmosphere,” Ehler said “Around the sun there’s a bluish glow. Different types and size distributions of dust will scatter light in unique ways.

Why can we see planets at night?

Even though planets are far away in space, many of them are visible at night during certain times. … Their visibility is determined by the interaction of light from the sun and the planets’ own shadows. Sometimes these planets become visible just after it begins getting dark.

Why do asteroids reflect different amounts of light?

The asteroid’s phase, just like the Moon’s, is changing as it orbits around the Sun (the larger the area of the asteroid that is illuminated, as seen from Earth, the brighter it will appear). The asteroid, because of its irregular shape, reflects light differently as it spins.
