comet
Yes, a comet experiences intense heating and friction as it enters Earth's atmosphere, causing it to burn and create a bright streak of light known as a meteor or shooting star. This process is due to the extreme speed at which the comet is traveling through the atmosphere.

The meteor is in the atmosphere and is only visible for seconds to minutes. The comet is much further away outside the atmosphere and can be observed for weeks to many months.
