Finders Keepers?

Meteorites can unlock secrets of the solar system. But who owns these space rocks?

As You Read, Think About: What do you think should happen to meteorites?

Imagine sitting in your house when—BOOM! There’s a loud crash nearby. That’s what happened three years ago in Brazil, in a village called Jacilândia. A rock landed near Adriano Gomes’s home. He told reporters that the noise was as loud as a plane. At first, he was afraid to touch the strange object.

His life quickly changed. Gomes learned this wasn’t an ordinary rock. It was a meteorite that had fallen from space. Collectors from faraway cities contacted Gomes. They offered him money, hoping to buy a piece of space.

But then an all-female team of scientists called As Meteoríticas reached out. They wanted the meteorite for a different reason: to study it. 

“Each meteorite is a piece of a puzzle that teaches us the history of our solar system,” says Maria Elizabeth Zucolotto. She’s a geologist and a member of As Meteoríticas. 

What would Gomes do with his once-in-a-lifetime find?

Rock Rush

DADO GALDIERI/The New York Times/Redux

Most meteorites start as pieces of asteroids, rocks that move around the sun. Some meteorites break off from the moon or Mars. Once a space rock makes it to Earth’s surface without burning up, it’s considered a meteorite. More than 70,000 meteorites have been found worldwide, about 2,000 in the United States. 

The meteorite Gomes found is called a chondrite, one of the oldest types of space rocks. It’s billions of years old.

This isn’t the first time space rocks rained down on Brazil. In 2020, more than 175 pounds of meteorites fell in a city called Santa Filomena. For weeks, residents searched the area for space rocks. Some people sold the meteorites they found to private collectors for thousands of dollars.

Zucolotto is a curator at the National Museum of Brazil. She worries that when meteorites are sold to collectors, scientists won’t get to examine them. And kids may never get the chance to see them in museums.

“When you hold a meteorite, it’s like you can touch space,” Zucolotto says. “It’s different than seeing it in a book.”

Who Owns Space?

So who really owns meteorites? The answer depends on where the rock is found. In the U.S., if a meteorite falls on a person’s property, it belongs to that person. In other places, like Canada and Mexico, meteorites can’t be removed from the country without permission.

Brazil has no clear rules. But scientists and lawmakers are discussing a new law. It would protect meteorites for research. But people who find them would be allowed to keep a piece.

“They’d need to give just a small piece of the meteorite to science,” Zucolotto explains. “They can do whatever they want with the rest of it.” 

What did Gomes do with his meteorite? In May, he sold it to Zucolotto’s team for about $900. And As Meteoríticas continues to travel around Brazil in search of other space rocks.  

“To find a meteorite is like a star falling into your hands,” Zucolotto says. “It’s magic.”

Mars On Earth

The biggest known meteorite from Mars was found in Niger, a country in Africa, in 2023. The 54-pound rock had broken off the Red Planet after an asteroid strike. It traveled 140 million miles through space before landing on Earth. 

In July 2025, the Martian meteorite was sold in New York City for $5.3 million. But Niger’s government says it should not have been taken out of the country. Sotheby’s, the auction house that sold the rock, says the sale was legal. Should space rocks belong to the country where they fall or to whoever pays the most?
