When the comet is far from the sun, it travels at about 2,000 miles per hour. As it gets closer to the sun, its speed increases. It may travel at over 100,000 miles per hour!

Which is faster comet or asteroid?
In fact, comets can be traveling up to three times faster than NEAs relative to Earth at the time of impact, Boslough added. The energy released by a cosmic collision increases as the square of the incoming object’s speed, so a comet could pack nine times more destructive power than an asteroid of the same mass.

What is the normal speed of a comet?
The average long-period comet will strike Earth with a velocity of 51.7 km (32.1 miles) per second. If the impact velocity is weighted by the probability of impact for a particular orbit, then the weighted mean impact velocity increases to 54.6 km (33.9 miles) per second.

What travels faster an asteroid or comet?
Because comets typically originate from farther out than asteroids do, they move at faster speeds when they cross Earth’s orbit: a comet would only need to be about ~7 kilometers in diameter to impact Earth with enough energy to create Chicxulub crater, while an asteroid would need to be a larger ~10 kilometers across.

Is a comet more powerful than an asteroid?
The energy released by a cosmic collision increases as the square of the incoming object’s speed, so a comet could pack nine times more destructive power than an asteroid of the same mass. The speed of comets also means that a dangerous one could be nearly upon Earth by the time scientists detect it.

How fast are asteroids?
Asteroids, the most common type of impactor, slam into the Earth at an average velocity of 18 km/s. Short-period comet impacts with the Earth are less common, but have higher impact velocities averaging 30 km/s. Even rarer are impacts from long-period comets at higher impact velocities that average 53 km/s.

How fast can a comet travel?
When the comet is far from the sun, it travels at about 2,000 miles per hour. As it gets closer to the sun, its speed increases. It may travel at over 100,000 miles per hour! As a comet approaches the sun, its icy body begins to melt, releasing gas and dust.

Can an asteroid travel faster than light?
Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It’s impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.

Why is Halley’s comet so fast?
The other unusual fact is I gleaned, is that Halley’s comet is retrograde travelling in the opposite direction to the planets. This makes it the fastest (known) object in the universe. 157,838 miles per hour. At this speed it could orbit the earth in 9.5 minutes.

What is the speed of Halley’s comet when it is nearest to Earth?
Halley’s Comet, appearing about every 76 years, is by far the brightest comet yet observed from earth. The comet’s perihelion is 88 million km at a velocity of 55 km/sec; its apihelion is 5.3 billion km at a velocity of 1 km/sec.

What is the maximum comet speed?
There are relatively big varieties, but most of them is between 10 and 70 km/s. If a comet is a periodic comet, that means it needs to have an elliptic orbit around the Sun. That gives an upper limit to its speed of the escape speed from the solar system on the orbit of the Earth. That is around 40 km/s.
