It's about one-nine-hundred-fiftieth as fast as The Speed of Light.
In other words, 955 mach is 0.00105617541 times the speed of The Speed of Light, and the speed of The Speed of Light is 946.8124240 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 904,205.8620 mach, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 602,803.9080 mach when passing through the glass of a typical window.
It's about three times as fast as a bolt of Lightning.
In other words, 955 mach is 3.20 times the speed of a bolt of Lightning, and the speed of a bolt of Lightning is 0.310 times that amount.(atmospheric electrical discharge)
A bolt of lightning can travel at up to 290 mach when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about seven-and-a-half times as fast as a Meteor.
In other words, the speed of a Meteor is 0.130 times 955 mach.(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 34 mach and 220 mach, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 8.40 mach.
It's about 40 times as fast as The Space Shuttle.
In other words, 955 mach is 40.890 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 0.024456 times that amount.(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 23.3560 mach. During liftoff, the space shuttle accelerates to orbital speed in 8.5 minutes, consuming over 1.59 million kg (3.51 million lbs) of propellant in the process.
It's about 350 times as fast as a Bullet (Rifle).
In other words, 955 mach is 346 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 0.00289 times that amount.(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 2.760 mach. As the NATO rifle cartridge, it is used by the military forces of more than thirty-one countries, including use in the M16 series, M4 Carbine, HK-416, and M249 Squad automatic weapons used by the United States armed forces.
It's about 450 times as fast as a Jet Fighter.
It's about 850 times as fast as a Bullet (Handgun).
In other words, 955 mach is 825 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 0.00121 times that amount.(for .40 Smith & Wesson 135 grain Sierra JHP, VV 3N37 powder, Fed. 100 primer, Remington case) (muzzle velocity)
A 0.40 caliber Smith & Wesson bullet has a muzzle a velocity of 1.160 mach. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
