What does observing a distinct yellow or orange tint usually imply about the vaporized material?
Answer
The material is likely Sodium or Iron
When analyzing the chemistry behind a meteor's color, distinguishing between atmospheric input and meteoroid composition is key. When the light signature is yellow or orange and is derived from the vaporization of the object itself, the elemental source is identified as either sodium or iron. Both of these metallic elements, upon being superheated during ablation, emit light strongly concentrated in the yellow-orange region of the spectrum. This contrasts with the emissions from magnesium (blue-green) or atmospheric nitrogen (red), allowing skywatchers to deduce the probable chemical constituency of the incoming space debris based on the resultant color.
