On August 16, the asteroid 2022 PW will pass at a distance of 1.4 LD (Lunar Distance). One LD is how far away the Moon is from the Earth.
According to NASA 's Center for Near Earth Object Studies (CNEOS), 2022 PW is traveling at a speed of around 7.5 km/s (about 17,000 mph) and is between 75 and 100 feet across, making it roughly the size of a Boeing 737-500, or a blue whale .
These Asteroid Particles May Be Our Most 'Pristine' Sample of The Outer Solar System : ...
According to a new, in-depth analysis of the material delivered to Earth from the asteroid Ryugu , the samples of rocks and dust are among the most uncontaminated Solar System materials we've ever had the opportunity to study – and their composition suggests that they incorporate chemistry from ...
Meteorites that reach the Earth fall from asteroid butts | Space
Every day, Earth is bombarded with about 48.5 tons (44 tonnes) of space rocks, dirt, and debris, according to NASA (opens in new tab) . Fortunately for us, the vast majority of it completely disintegrates in our atmosphere.
Scientists have long wondered exactly how meteorites survive the fiery entry through the atmosphere, during which meteors heat up to some 3,000 degrees Fahrenheit (1649 degrees Celsius).

New Evidence Suggests Giant Asteroid Impacts Created Earth's Continents
Earth is the only planet we know of with continents , the giant landmasses that provide homes to humankind and most of Earth's biomass .
However, we still don't have firm answers to some basic questions about continents: how did they come to be, and why did they form where they did?
Astonishing! NASA says dangerous asteroids about to hit Earth CANNOT be shot down | Tech News
With so many asteroids flying left and right past the Earth these days, scientists realize it is a question of when and not if an asteroid will strike the Earth. Just last week, the Earth witnessed four different asteroids approaching dangerously close to it.
On the FAQ section of its Planetary Defense webpage, NASA states, "An asteroid on a trajectory to impact Earth could not be shot down in the last few minutes or even hours before impact.
@RefetovaRoxana No Known Asteroid Poses an Impact Threat to Earth for at Least the Next ...

TOKYO : Water and organic matter was brought to Earth by asteroids, finds Japan's Hayabusa2 space probe.
The findings, published in the scientific journal Nature Astronomy explains the mystery of how the Earth, which consisted almost entirely of molten magma in its initial formation, came to be covered in water, Kyodo News reported.
Meteor Shower: What's the difference between a meteor, meteoroid, and meteorite?
SALT LAKE CITY ( ABC4 ) – What’s the difference between a meteor, meteoroid and meteorite?
A meteor, like the one seen over Utah on Saturday, is classified as “the streak of light” that you see in the sky when “a small piece of cometary or asteroidal material” enters the atmosphere at high speed and burns up.
This Week in Space: A Telescope, A Bugbot, and Betelgeuse Blows its Stack - ExtremeTech
Hello, lovelies, and welcome to your favorite roundup of space news: the one corner of current events that doesn’t suck. This week, we’ve got lots of updates from NASA. For one thing, the agency is building a six-mile-wide space telescope.
Betelgeuse is the bright red star that forms Orion’s right shoulder. The star caught scientists’ attention in late 2019 when it started going dim. It’s been fluctuating in brightness since then, with little clue as to why.
