ESO images “dog bone” asteroid called Kleopatra in detail

At the European Southern Observatory, Astronomers have leveraged the Very Large Telescope to take the most detailed images of a peculiar asteroid known as Kleopatra. The asteroid is shaped like a dog bone and is quite large at 270 kilometers. To put its size in perspective, 270 kilometers is roughly half the length of the English Channel.

New theory proposed about asteroid Vesta

New theory proposed about asteroid Vesta

There are many large asteroids in our solar system, and one called Vesta is the second largest of them all. Vesta has a diameter of about 330 miles. It's located between the orbits of Mars and Jupiter. NASA has previously investigated Vesta with a program called Dawn that launched in 2007.

Blazing fast asteroid orbits the sun in 113 days

Blazing fast asteroid orbits the sun in 113 days

Astronomers have discovered what they say is the fastest orbiting asteroid in the solar system. The asteroid orbits the sun in 113 days, giving it the shortest known orbital period for an asteroid and the second shortest orbital period for any object in the solar system. The only object in the solar system with a faster orbital period than the new asteroid, called 2021 PH27, is the planet Mercury.

A giant asteroid buzzed the Earth yesterday

A giant asteroid buzzed the Earth yesterday

A gigantic asteroid that is considered potentially hazardous by NASA zipped past the Earth yesterday at a very high rate of speed. The asteroid, called 2016 AJ193, flew past the Earth at a velocity of 58,000 mph. It's hard to imagine a speed that high; it equates to traveling about 16 miles every second.

NASA’s DART spacecraft moves closer to launch

NASA’s DART spacecraft moves closer to launch

NASA has been hard at work on multiple missions, and one of those missions is called DART. Earlier this month, the spacecraft was sitting in the middle of its cleanroom, having its solar arrays coiled into a pair of cylinders on each side of the spacecraft. As DART gets closer to launch, NASA is talking about some of the technology that will be used for the mission.

NASA investigates the comet-like activity of asteroid Phaethon

NASA investigates the comet-like activity of asteroid Phaethon

NASA scientists have been studying an interesting asteroid called Phaethon that is exhibiting comet-like activity. Recent laboratory models and tests have suggested that the asteroid could be venting sodium vapor as it orbits near the sun. That bidding could explain the increase in brightness observed by scientists.

Pyramid-sized asteroid to pass by the Earth today

Pyramid-sized asteroid to pass by the Earth today

Most people are probably familiar with the pyramids in Egypt, particularly the largest known as the Great Pyramid of Giza. An asteroid about the size of that pyramid will pass by the Earth today with no chance of impact. The asteroid is called 2008 GO20, and it will fly by the Earth on July 25, 2021.

Chinese proposal would deflect asteroids using rockets

Chinese proposal would deflect asteroids using rockets

While the potential is very low, there is a chance that at some point, an asteroid could impact the Earth. While most asteroids are small enough to cause little damage on the ground, the potential for a larger asteroid that could have drastic consequences for life on Earth can't be ignored. Massive asteroids have impacted the Earth in the distant past, with the most famous being responsible for the extinction of the dinosaurs.

An asteroid the size of the Eiffel tower will whiz past the Earth next month

An asteroid the size of the Eiffel tower will whiz past the Earth next month

An asteroid will fly past the earth next week that is believed to be taller than the Eiffel Tower. NASA has dubbed the asteroid as potentially hazardous, but it is expected to pass by the earth safely. Asteroids are investigated by examining their size and distance from the Earth to determine if they pose a potential hazard.

OSIRIS-REx is on its way home packed with asteroid samples

OSIRIS-REx is on its way home packed with asteroid samples

The NASA OSIRIS-REx spacecraft has spent nearly half a decade in space and has finally departed asteroid Bennu and is on its way back to Earth. NASA has announced that on Monday, May 10 at 4:23 PM EDT the spacecraft fired its main engines full throttle for seven minutes. The firing of its main engines represents the most significant maneuver for the spacecraft since it arrived at Bennu in 2018.

The results of the 2021 asteroid impact simulation highlight threats posed by asteroids

Recently scientists participated in an international exercise meant to simulate the effects of an asteroid striking the earth. The exercise simulated that a 460-foot-wide asteroid that would impact Central Europe. The specific region was a 185-mile-wide zone bordering Germany, Austria, and the Czech Republic.

China may build an asteroid defense system

China may build an asteroid defense system

China has announced that it intends to have discussions on building a defense system to help protect the planet against near-Earth asteroids. Word of the talks comes as China has promised to increase its ambitions for longer-term missions in space. China has been focusing on space missions in recent years and not long ago said that it would work with Russia to build a space station and possibly a lunar base.
