An asteroid the size of an SUV passed 1,830 miles (2,950 kilometers) above Earth, the closest asteroid ever observed passing by our planet, NASA said Tuesday.

If it had been on a collision course with Earth, the asteroid -- named 2020 QG -- would likely not have caused any damage, instead disintegrating in the atmosphere, creating a fireball in the sky, or a meteor, NASA's Jet Propulsion Laboratory (JPL) said in a statement.

The asteroid, which was about 10 to 20 feet (three to six meters) long, passed above the southern Indian Ocean on Sunday at 0408 GMT.

It was moving at nearly eight miles per second (12.3 kilometers per second), well below the geostationary orbit of about 22,000 miles at which most telecommunication satellites fly.

The asteroid was first recorded six hours after its approach by the Zwicky Transient Facility, a telescope at the Palomar Observatory at the California Institute of Technology, as a long trail of light in the sky.

The US space agency said that similarly sized asteroids pass by Earth at a similar distance a few times per year.

But they're difficult to record, unless they're heading directly towards the planet, in which case the explosion in the atmosphere is usually noticed -- as in Chelyabinsk, Russia in 2013, when the explosion of an object about 66 feet long shattered windows for miles, injuring a thousand people.

One of NASA's missions is to monitor larger asteroids (460 feet) that could actually pose a threat to Earth, but their equipment also tracks smaller ones, AFP reported.

"It's really cool to see a small asteroid come by this close, because we can see the Earth's gravity dramatically bends its trajectory," the news agency quoted Paul Chodas, the director of the Center for Near-Earth Object Studies at NASA, as saying.

According to the JPL's calculations, the asteroid turned by about 45 degrees due to Earth's gravitational pull.

More than a dozen tigers were incinerated after the animals contracted bird flu at a zoo in southern Vietnam, officials said.
State media VNExpress cited a caretaker at Vuon Xoai zoo in Bien Hoa city saying the animals were fed with raw chicken bought from nearby farms, The Associated Press reported. The panther and 20 tigers, including several cubs, weighed between 10 and 120 kilograms when they died. The bodies were incinerated and buried on the premises.
“The tigers died so fast. They looked weak, refused to eat and died after two days of falling sick,” said zoo manager Nguyen Ba Phuc.
Samples taken from the tigers tested positive for H5N1, the virus that causes bird flu.
The virus was first identified in 1959 and grew into a widespread and highly lethal menace to migratory birds and domesticated poultry. It has since evolved, and in recent years H5N1 was detected in a growing number of animals ranging from dogs and cats to sea lions and polar bears.
In cats, scientists have found the virus attacking the brain, damaging and clotting blood vessels and causing seizures and death.
More than 20 other tigers were isolated for monitoring. The zoo houses some 3,000 other animals including lions, bears, rhinos, hippos and giraffes.
The 30 staff members who were taking care of the tigers tested negative for bird flu and were in normal health condition, VNExpress reported. Another outbreak also occurred at a zoo in nearby Long An province, where 27 tigers and 3 lions died within a week in September, the newspaper said.
Unusual flu strains that come from animals are occasionally found in people. Health officials in the United States said Thursday that two dairy workers in California were infected — making 16 total cases detected in the country in 2024.
“The deaths of 47 tigers, three lions, and a panther at My Quynh Safari and Vuon Xoai Zoo amid Vietnam’s bird flu outbreak are tragic and highlight the risks of keeping wild animals in captivity,” PETA Senior Vice President Jason Baker said in a statement sent to The Associated Press.
“The exploitation of wild animals also puts global human health at risk by increasing the likelihood of another pandemic,” Baker said.
Bird flu has caused hundreds of deaths around the world, the vast majority of them involving direct contact between people and infected birds.
