They emmit light because they have many stars.
Things that emit include light bulbs, the sun, and fire, which release energy in the form of light and heat. Things that reflect include mirrors, glass windows, and shiny surfaces, which bounce light off them without absorbing it.
stars,metiorite and the sun emit light,comites do both. other than that the moon and the planets reflect light
Earth both reflects and emits light. The surface of the Earth reflects sunlight, which is why we can see it during the day. Earth also emits infrared radiation (heat) back into space, which is absorbed by greenhouse gases in the atmosphere.
emit light means you produce the light, to reflect the light is to "re-show" the light that something else made.
Stars generate and radiate their own light. This is pretty obvious when you think about the star that's closest to us ... the sun.
All planets only reflect light. Only stars, like our sun, emit.
the sun only emit light. not the moon. it will reflect the light of the sun.
The planets do not emit light, they reflect sunlight.
It is a star, so it emits light.
No. Planets and moons reflect light.
No. Planets do not emit light; they can only reflect light from the Sun.
The sun emits light, and quite a lot of it.
Planets do not emit their own light; instead, they reflect light from the Sun. This reflected sunlight allows us to see planets shining in the night sky. The amount of light reflected depends on the planet's surface composition and atmosphere.
It seems readily apparent that trees reflect light, since you don't see them glowing at night.
A star emits light. Our Sun is a star.
The Moon only reflects light from the Sun.
Stars do not reflect light from the Moon or the Sun. Stars emit their own light due to nuclear fusion reactions happening in their cores. The light we see from stars is the result of this emission, not reflection.
