NASA’s Lucy asteroid mission already faced a busy itinerary with seven different space-rock targets. Now, the team has discovered that one of those asteroids has a tiny companion.
The realization came thanks to the Hubble Space Telescope , which the team first recruited in 2018 to study a space rock called Eurybates. Like several of the other Lucy mission targets, Eurybates belongs to a group of asteroids known as Trojans, which occupy about the same orbit around the sun as Jupiter but cluster ahead of or behind the gas giant.

See the big asteroid 1998 OR2 just before its Earth flyby in a Slooh webcast today | Space
A big asteroid will safely fly by Earth early tomorrow morning (April 29), and you can watch it approach our planet in real time tonight with a free webcast from the Slooh online observatory.
The one-hour public event will commence just 11 hours before asteroid 1998 OR2 will make its closest approach to Earth, tomorrow at 5:56 a.m. EDT (0956 GMT). At that time, the asteroid will be about 3.9 million miles (6.3 million kilometers) from Earth, or about 16 times the average distance between Earth and the moon.
Near-Earth asteroid Ryugu went on an 'orbital excursion' toward the sun - CNN
(CNN) When the Japan Aerospace Exploration Agency's Hayabusa2 spacecraft briefly touched down on near-Earth asteroid Ryugu, scientists noticed two different colors of material on the asteroid's surface.
Largest Impact Event in Recorded History May Have Been An Iron Asteroid That Never Actually Hit
The largest impact event in recorded history may have been caused by the shock waves generated by an iron asteroid that entered the Earth’s atmosphere at a shallow angle before heading back into space, a team of Russian scientists have proposed.
The researchers say that the massive explosion associated with the event may not not have been caused by a space object that fell towards the ground, as is generally believed, potentially explaining the almost total absence of meteorite fragments on the Earth’s surface, according to a study published in the journal Monthly Notices of the Royal Astronomical Society .

On May 4th, a tiny asteroid missed Earth… but just barely - India Gone Viral
Before you panic, at this diameter (about the size of a car) it wouldn’t have done any real damage even if it had hit us. But it would’ve put on a helluva show, creating an intensely luminous fireball easily brighter than the full Moon as it burned up and broke apart in our atmosphere, probably a few dozen kilometers above the Earth’s surface. It's also likely small pieces would've made it to the ground as meteorites, too.
This part made the hairs on the back of my neck stand up: For a short time, before observations had nailed down its trajectory, there was a 5% chance of impact! I know those aren't short odds — a 1 in 20 chance is pretty low † — but still that's high for an impact. Of course, like I said, even if it had hit it wouldn't have been dangerous. Just spectacular.
Japanese asteroid probe discovers space rock Ryugu made close pass of Sun
Hyderabad : Japan's Hayabusa2 asteroid probe has already accomplished a lot. After launching in 2014 and spending several years travelling to intercept the space rock known as Ryugu, it made many key observations and even took samples of the asteroid before departing and heading back to Earth.
The Hayabusa2 spacecraft built and operated by the Japan Aerospace Exploration Agency (JAXA), fired a 5-g metal projectile into the surface of the near-Earth asteroid Ryugu, a spinning top-shaped body with 1 km across and some 350 million km from Earth. This projectile disrupted the surface of the asteroid, allowing Hayabusa2 to capture some of the lofted material and tuck it safely away on board.
JOHN HUMPHRYS: An asteroid could be heading for Earth and yet our leaders are at war with each
Every leader of every country in the world had come together on a virtual network. Never had there been such a conference.
But never had there been such a crisis. The very existence of our fragile planet was threatened by a massive asteroid bearing down on us at phenomenal speed.
Back in April 2020, the world had watched with mild interest as a large lump of rock dubbed as 'potentially hazardous' had zipped across our night skies — close enough to be noted but not close enough to be a serious threat.
Meteorite hunting, and how to tell the difference between a space rock and an Earth rock - ABC
If you look up at the sky at night for long enough, you're nearly guaranteed to see a shooting star: a bright, fine light zipping across the sky.
Shooting stars, or meteors, are often the last we'll see of the rock that caused their bright flash in the sky as it burns up in our atmosphere.
Most of the time, the object that caused the shooting star is no larger than a grain of sand, and not much will make it to earth.

The Desert Fireball team from Curtin University have set up cameras across Australia to monitor for big meteors, fireballs, that might leave behind meteorites, to try and track them down quickly.
