What is a fiery ball?

Fireball is a meteor that appears to be a human eye to have a brightness straight or greater than the brightness of Venus when it is visible in the sky. To achieve this level of brightness, the meteor is usually relatively large and occasionally falls to the Earth's surface without being destroyed as it passes through the atmosphere. Fireballs are in fact a relatively common occurrence, but often occur in daylight or in unpaid areas. They may seem like different colors followed by trails, and also generate sounds in rare cases. If the fireball explodes with a clear flash, it is known as the bolide.

The very clearly lit meteor is often referred to as a fireball. According to astronomy experts, the exact definition is that the meteor must seem at least as clear as Venus when you can see in the evening or morning areas. According to a commonly used brightness scale, Venus is a -4 size, while the measurement further along the negative scale appears brighter; For example, the full moon has a size of -12.6. To make a fiery ball visibleIn daylight, it must be at least -6 sizes -more if it seems near the sun.

generally to be clear enough to be categorized as a fireball, the meteor must be relatively large. Some are actually large enough to safely pass through the Earth's atmosphere without burning and falling on the planet's surface, but it is a relatively rare occurrence. It is estimated that thousands of fiery balls occur in the Earth's atmosphere daily. Most of the fiery balls are never recorded and reported because they occur in unpopulated areas or appear during daylight and are not clear enough to be seen.

Fireballs can be very different in appearance and duration. They may seem like different colors, from red to bright blues and purple; It is believed that these shades arise from extreme heating and other substances whose meteors are composed. It seems to be fieryThe balls often have a trace that can be made of smoke and visible during the day, or show a shining "train" of excited and ionized air molecules that are usually seen at night. Fireball and its trail can be visible for different durations from a few seconds to more than a minute. Anyone wants to report observations should notice the general appearance, color, placement and duration of the phenomenon, and then pass this information to the scientific organization for the region.
