A fireball occurs when a meteoroid enters Earth's atmosphere and burns up due to friction with the air. Mercury has a very thin atmosphere, so there are not enough particles to create the friction needed for a fireball to form.
Gases and particles in the atmosphere scatter sunlight in all directions, causing the sky to appear blue and sunsets to appear red. They also absorb certain wavelengths of light, leading to phenomena like Rayleigh scattering and the greenhouse effect. Overall, these interactions determine the color of the sky, influence the Earth's energy balance, and play a crucial role in climate regulation.

Scattering of light occurs when light interacts with particles of matter and is redirected in different directions, causing it to spread out. This phenomenon can cause the sky to appear blue during the day due to scattering of sunlight by atmospheric gases and particles.
Gases and particles in the atmosphere can scatter and absorb light rays as they pass through. Scattering occurs when the light rays are redirected in various directions, while absorption involves the particles absorbing the light energy. These interactions with gases and particles can affect the color and intensity of sunlight reaching the Earth's surface.
An aurora occurs when charged particles of the sun excite the electrons of atoms in Earth's atmosphere. The moon does not have an atmosphere.
Diffusion of light in the atmosphere occurs due to interactions of light with air molecules, dust, and water droplets. These particles scatter sunlight in all directions, leading to the blue appearance of the sky and the red hues seen during sunrise and sunset.
Mie scattering occurs when particles are larger than the wavelength of light, causing light to scatter in all directions equally. Rayleigh scattering happens when particles are smaller than the wavelength of light, leading to shorter wavelengths being scattered more than longer ones.
