An asteroid just zipped past Earth closer than the moon's orbit | Space
Asteroid 2021 TG14 passed by Earth at a distance of roughly 155,000 miles (250,000 km). That's well within the orbit of our moon , which orbits at an average distance of nearly 239,000 miles (385,000 km).
NASA is always interested in close passes like this, just in case astronomers can get some valuable telescope time for a rare close-up glimpse of a small world.
NASA Will Smash A Spacecraft Into An Asteroid To Trial Saving The Planet
Dinosaurs had no warning and no way to defend themselves when an asteroid suddenly destroyed their existence 65 million years ago. Humans, understandably, want to avoid the same fate.
A space program might protect humans from space-based threats, like massive asteroids headed toward Earth. With this in mind, NASA wants to smash a spacecraft into an asteroid in a rehearsal of saving Earth from a hypothetical asteroid catastrophe.
Scientists solve the mystery of asteroid's surprisingly rugged surface - SCIENCE News
As the OSIRIS-ReX throttles towards Earth with first samples from the surface of an asteroid, scientists are already making strides in understanding the surface features of the object.
Researchers found it was the asteroid's highly porous rocks that were responsible for its surprisingly lack of fine regolith (fine-grained material smaller than a few centimetres).

Between 2.5 and 4 billion years ago, a time known as the Archean eon, Earth's weather could often be described as cloudy with a chance of asteroid.
NASA: Asteroid the size of Empire State Building to whiz close by Earth in coming weeks
The aircraft started its 12 year journey early Saturday morning, heading towards Jupiter's orbit in order to find more secrets and clues about the history of the solar system.
Huge asteroids — the sizes of cars, houses, a commercial jetliner and the Empire State Building — have and will come close to Earth in the coming weeks, according to NASA’s Jet Propulsion Laboratory.

Nasa's asteroid missions could reveal our origins and help save us | The Independent
Space rocks are generally considered to be asteroids if they are larger than approximately 1km in size, and made principally of "non-volatile" materials – chemicals which can be easily vaporised. Carbon monoxide, for example, is volatile as it vaporises at a temperature of -191C.
This is somewhat different to comets . Asteroids are found more commonly in the inner solar system, whereas comets with their volatile-rich composition tend to lurk in the outer part, far from the heat of the sun.
Spacecraft for asteroid deflection experiment ready for fueling – Spaceflight Now
A small spacecraft built for a NASA asteroid defense experiment arrived at Vandenberg Space Force Base in California earlier this month and is ready for fueling, one of the final milestones before liftoff in November on a SpaceX Falcon 9 rocket.
NASA’s Double Asteroid Redirection Test, or DART, spacecraft arrived at Vandenberg on Oct. 2 after a cross-country trip by truck from the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.
Space Mining: Scientists Discover Two Asteroids Whose Precious Metals Would Exceed Global Reserves
However, the NASA plans to merely orbit and document 16 Psyche, and in any case won't reach the asteroid—situated in the asteroid belt between Mars and Jupiter—until 2026.
Now researchers have uncovered two metal-rich near-Earth asteroids (NEAs) that could one day be mined for iron, nickel and cobalt could for use on Earth or in space.
