How fast is 549 kilometers per second?

Sort Order:
Closest first | Highest first | Lowest first

It's about five-and-a-half times as fast as a bolt of Lightning.
In other words, the speed of a bolt of Lightning is 0.180 times 549 kilometers per second.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 97 kilometers per second when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about thirteen times as fast as a Meteor.
In other words, the speed of a Meteor is 0.077 times 549 kilometers per second.
(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 11 kilometers per second and 72 kilometers per second, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 2.80 kilometers per second.
It's about 70 times as fast as The Space Shuttle.
In other words, 549 kilometers per second is 70.8970 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 0.014105 times that amount.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 7.74360 kilometers per second. 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 one-five-hundred-fiftieth as fast as The Speed of Light.
In other words, 549 kilometers per second is 0.0018312668826379 times the speed of The Speed of Light, and the speed of The Speed of Light is 546.07005100181 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 299,792.4580 kilometers per second, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 199,861.638670 kilometers per second when passing through the glass of a typical window.
It's about 600 times as fast as a Bullet (Rifle).
In other words, the speed of a Bullet (Rifle) is 0.00167 times 549 kilometers per second.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 0.9150 kilometers per second. 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 800 times as fast as a Jet Fighter.
In other words, 549 kilometers per second is 820 times the speed of a Jet Fighter, and the speed of a Jet Fighter is 0.0012 times that amount.
(for Lockheed Martin F-16, a.k.a. Fighting Falcon, a.k.a. Viper) (maximum speed at altitude)
An F-16's maximum speed at altitude is approximately nan kilometers per second. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about 1,500 times as fast as a Bullet (Handgun).
In other words, 549 kilometers per second is 1,430 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 0.000699 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 0.3830 kilometers per second. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
