 It's about 0.00000002 times as fast as a Meteor. In other words, 123 inches per hour is 0.0000000210 times the speed of a Meteor, and the speed of a Meteor is 48,000,000 times that amount. (formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")Small meteoroids enter the Earth's atmosphere at speeds between 1,600,000,000 inches per hour and 10,000,000,000 inches per hour, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 390,000,000 inches per hour. It's about 0.000000009 times as fast as a bolt of Lightning. In other words, 123 inches per hour is 0.00000000890 times the speed of a bolt of Lightning, and the speed of a bolt of Lightning is 110,000,000 times that amount. (atmospheric electrical discharge)A bolt of lightning can travel at up to 14,000,000,000 inches per hour when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year. It's about 0.000000000003 times as fast as The Speed of Light. In other words, 123 inches per hour is 0.000000000002894780410 times the speed of The Speed of Light, and the speed of The Speed of Light is 345,449,346,000 times that amount. (C) (in a vacuum)The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures exactly 42,490,269,600,000 inches per hour, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 28,326,846,400,000 inches per hour when passing through the glass of a typical window.
