Comets

2019 TA7 is classified as a near-Earth object because its orbit around the sun takes it within 121 million miles of the star, and 30 million miles of Earth.

The Perseids are the result of debris being released from the comet 109P/Swift-Tuttle as it speeds past the Earth in its orbit around the sun.

The space rocks will all fly by past our planet on Saturday in quick succession.

The crucial compounds could have been brought to Earth by comets or asteroids.

The comet is currently flying towards the inner Solar System at speeds of more than 51,000 miles per hour.

The comet is currently travelling through space at speeds of more than 51,000 miles per hour

Several eyewitnesses in the southeastern United States reported seeing the bright object.

The video also shows stars, asteroids and even an arc of stray light from Mars.

In two weeks, the comet will travel closer to the Sun than Mercury.

"We [may] have at our fingertips the starting materials of planet formation from 4.6 billion years ago."

Scientists have been studying the compounds in asteroids for decades.

The space instrument COSIMA has collected 35,000 particles of dust from the comet.

Events like these occur dozens of times each year. Why was this one special?

NASA may not be that swift in detecting the hazards, but your odds of getting killed by an asteroid are roughly one in 700,000.

The two finalists for a future mission now have to prove their worthiness.

What if humans could take over meteor showers and make them perfect Instagram fodder?

Exocomets are hard to spot, but they're definitely out there.

Scientists aren't sure what it is or where it came from, but they're positive it's pretty weird.

You'll need a pair of good binoculars and a little patience.

The best method for destroying a huge asteroid that is headed towards Earth that I've come across is to explode a thermonuclear warhead a few miles above the surface.

Scientist traces the trajectories of 300,000 stars and found the ones most likely to brush past us in the future.

Understanding these comets is important, as they could have delivered icy materials to Earth—and may affect the planet in the future.

The space agency is hosting a 24-hour broadcast on what asteroids are and the risks they pose if they were to collide with Earth.

Tomorrow is Asteroid Day—an annual event to highlight the risks asteroids pose to Earth.

The event was captured by amateur astronomers.

The asteroid will pass relatively close to our planet.

The good news ends there.

Luckily, there were no reports of damage.

A new study is the first ever to show that impacts may create peptide chains.

Probe "speaking" for first time since its botched landing on a comet in November.
