The rock was 2ft in diameter and weighed 1,000lbs, NASA said before it broke into small pieces and scattered across the area.
No damage was reported, but terrified locals assumed it was an earthquake and shared stories on social media of their homes shaking with the impact.
NASA said that anyone who thinks they have found a fragment must contact the Smithsonian.
They reassured people that the space rocks posed little threat to the public.
NASA on Thursday released this chart showing the debris over McAllen. Yellow areas are believed to have received rocks of up to 1g in size, while in the red zone they could be up to 1,000g
‘Although meteorites tend to hit Earth’s atmosphere at high speeds, they slow as they travel through the atmosphere, breaking into small fragments before hitting the ground,’ NASA said.
‘Meteorites cool rapidly and generally are not a risk to the public.’
The rock beamed through the sky around 5pm on Wednesday before a boom was heard.
Footage showed the fiery object shooting through the sky as home surveillance cameras caught the moment it crashed – creating a loud explosion and shaking homes.
The National Weather Service reported the object and claimed their satellites that detect light from space picked up on the signal. The agency then plotted the occurrence on its Geostationary Lightning Mapper.
Houston Air Traffic Control also received reports from two planes about a possible meteorite near the town, according to Hidalgo County Sheriff Eddie Guerra.
A meteor is referred to as a meteorite until it hits the ground.
‘Where the exact point of impact is unknown,’ Guerra said. ‘No reports of any damage in that area has been received.’
One woman said she thought it was an earthquake.
‘I went outside to see what had happen,’ she wrote on Facebook.
‘I thought it was some kinda earthquake but saw nothing. So strange we don’t have earthquakes here in Texas.’
Another described it to feel similar to a ‘gas explosion.’
‘So, we had a loud boom, like a gas explosion this afternoon,’ one person wrote. ‘The ground shook so did the windows and house too.’
A massive meteorite was seen speeding over South Texas on Wednesday afternoon. NASA confirmed it on Thursday
Meteoroids are bits of asteroids that have broken off, once they enter Earth’s atmosphere they become meteors. An asteroid the size of Mt Everest is what led to the extinction of the dinosaurs.
Astrophysicist Neil Degrasse Tyson recently appeared on CBS This Morning to discuss how officials are preparing to save Earth and combat asteroids – following one appearing in Northwestern Europe on Monday.
‘We’ve always known we don’t want to get hit,’ Tyson said.
‘We’ve been hit – and let’s talk to the dinosaurs about what happens when you get hit.
‘We remember the dinosaurs because they have big teeth and they are ferocious – but few people think about that 70 percent of all the world’s species – of life – went extinct in that very same episode.’
Tyson continued: ‘Little ones can come, and maybe we won’t go extinct, but it can take out our grid, and we might have to jump-start civilization.’
The Astrophysicist called the operation to stop asteroids as ‘the most expensive mission’ and said it wasn’t as simple as simply ‘blowing it up.’
Earlier this week, an asteroid lit up the night sky over the English Channel after entering the Earth’s atmosphere in the early hours on Monday.
The 3ft meteoroid created a shooting star and an ‘airburst’ that could be seen across southern England and Wales and in parts of northern France as far south as Paris.
The rock, called 2023 CX1, entered the atmosphere around two miles off the French coast at 3am, creating a fireball as it disintegrated into small pieces which landed in the sea.
It was only the seventh time an asteroid strike had been successfully forecast, in what the European Space Agency said was ‘a sign of the rapid advancements in global asteroid detection capabilities’.
For scientists, forecasting harmless asteroids like this morning’s one is seen as good practice for detecting ones that could pose a risk to the planet.
Explained: The difference between an asteroid, meteorite and other space rocks
An asteroid is a large chunk of rock left over from collisions or the early solar system. Most are located between Mars and Jupiter in the Main Belt.
A comet is a rock covered in ice, methane and other compounds. Their orbits take them much further out of the solar system.
A meteor is what astronomers call a flash of light in the atmosphere when debris burns up.
This debris itself is known as a meteoroid. Most are so small they are vapourised in the atmosphere.
If any of this meteoroid makes it to Earth, it is called a meteorite.
Meteors, meteoroids and meteorites normally originate from asteroids and comets.
For example, if Earth passes through the tail of a comet, much of the debris burns up in the atmosphere, forming a meteor shower.
