So how do we get these metals from these faraway asteroids? Perhaps the best way is to bring the space rocks to Earth.
Those asteroids are the fragmented remains of almost-planets, but they contain all of the same mixtures of elements as their larger planetary cousins.

Why it matters: Asteroids are thought to be key to unlocking exactly how planets and other bodies formed from a roiling mass of gas and dust orbiting the Sun billions of years ago.
State of play: Researchers have been studying asteroids for decades, but current missions will deliver to Earth some of the first direct samples from asteroids, allowing scientists to study them with high-powered instruments on the ground.
Astro Bob: Have a small scope? Take a peek at Hebe | Park Rapids Enterprise
Thousands of known asteroids ply the summer nighttime sky. But only a dozen or so are currently bright enough to spot in a small scope. One of the easiest is 6 Hebe (HEE-bee) with a diameter of about 116 miles (186 km).
The number "6" in front of Hebe's name tells us that it was the sixth asteroid discovered. German amateur astronomer Karl Ludwig Hencke found it the night of July 1, 1847. Around the time of its discovery our understanding of these small objects was in transition.
Astronomers capture most detailed images of large, rare metal asteroid – Physics World
Astronomers have used the Atacama Large Millimeter/Submillimeter Array (ALMA) to gain a more detailed picture of the composition of the asteroid Psyche.
Psyche was discovered in 1852 by the Italian astronomer Annibale de Gasparis. It is classed as an M-type asteroid, meaning that its spectrum resembles that of an iron meteorite, and its diameter of more than 200 km means that it is the largest of its kind ever found.
Buhl Planetarium & Observatory Tracks Path Of Asteroid Set To Pass By Earth – CBS
PITTSBURGH (KDKA) — An asteroid larger than the Empire State Building is going to have a close pass-by with Earth this weekend, but the experts at Pittsburgh’s Buhl Planetarium & Observatory say there is no need for worry.
The asteroid is over 2,000 feet in diameter and is going to be about two million miles away from Earth, says Buhl Planetarium producer Charissa Sedor.
The fastest-known asteroid in the solar system was just discovered | TechRadar
Astronomers just discovered the fastest-known asteroid in the solar system, which tore through its latest long, elliptical lap around the sun in just 113 days, getting so close to the star on its nearest approach that its surface was hot enough to melt lead.
The space rock, designated 2021 PH27, has the shortest orbital period of any known object in the solar system other than Mercury – which has an orbital period of a mere 88 days – but 2021 PH27 does have a longer elliptical orbit that crosses both Mercury's and that of Venus.
NASA moves closer to launching its 'asteroid deflecting' spacecraft | TweakTown
NASA has just taken a few steps towards the launch of the spacecraft that is designed to collide with an asteroid.
NASA is calling it the Double Asteroid Redirection Test, or DART for short. The mission is to see if NASA is capable of designing a spacecraft that's purpose is to collide with an asteroid to knock it off course.
We May Finally Know The Secret of The Geminids Asteroid's Weird Comet-Like Tail
There's something strange about the near-Earth asteroid 3200 Phaethon : It brightens up as it approaches the Sun, despite not having any reserves of ice that would normally cause this effect as they evaporate and scatter sunlight.
It is ice-laden comets that get brighter as they're heated, not rocky asteroids, which is why Phaethon has long puzzled astronomers. Now a new study suggests that one chemical element in particular might be behind this bizarre behavior.
Phaethon is an actual Pop Rock of an asteroid because of sodium outgassing
If asteroids don't normally have tails like comets , then what is that thing, which is clearly not made of ice, streaking across the void with what is very obviously a vapor trail behind it?
Comet tails result from ices vaporizing into space with solar heat, taking particles of dust and rock with them. Asteroids usually have no tails because most are solid rock.
