Perseus has a green and orange meteor. What color will appear next time?

Perseid meteor is one of the favorite astronomical phenomena seen by countless astronomy enthusiasts.

Perseid meteor shower, the moon covering Venus, Venus' westward distance, Mercury's westward distance, Mars, Saturn and Neptune will appear together. Among them, Perseid meteor shower can let people enjoy dozens of beautiful yellow-green meteors in an hour.

As one of the three major meteor showers in the northern hemisphere, the Perseid meteor shower is extremely popular in mid-August every year, and its eruption allows the public to enjoy dozens of beautiful yellow-green meteors in an hour.

When the annual Perseid meteor shower came, countless sky observers witnessed hundreds of green meteors and saw green fireballs falling from the sky. The scene looks beautiful and spectacular. David blanchard, a photographer from Stafford, Frug, Arizona, captured a very "green" meteor when he was exposed with a Nikon digital camera for 30 seconds. The photos look great.

In fact, the color composition of meteors is different from that of ordinary stars. The former is mainly composed of emission lines. Some of the so-called emission lines are very Ming Rui-colored. For example, we use a spectroscope to shoot the meteor spectrum, and there are obvious orange-yellow sodium lines, green magnesium lines (this green color is slightly blue), and some red nitrogen-oxygen lines and blue iron lines.

Science explains that when a sodium-rich celestial body passes through the atmosphere, the hot sodium vapor will emit yellow light like a sodium-containing radiation lamp. Of course, the colors of meteors photographed in different areas will be different. A sky observer in Alabama, USA, captured a rare photo of a meteor, which showed that a meteor had drawn an orange arc trajectory.

Because the matter produced by meteors is basically unchanged, the color will not change much.
