Asteroid 2025 OU1 zooms past Earth today: Key details
NASA is tracking asteroid 2025 OU1 as it swings by Earth on July 26, 2025.
The space rock is about 43m wide and will pass us at over 66,000km/h—still more than four times farther away than the Moon.
It's not big or close enough to be a "potentially hazardous" asteroid, but NASA scientists are keeping tabs on its path just in case.
NASA's tracking helps global asteroid watch efforts
Even though OU1 will stay over 1.66 million km from Earth, experts are interested in tiny shifts in its orbit since these can matter for future flybys.
You won't spot this one with the naked eye—it takes pro telescopes and radar—but NASA's advanced tracking helps sharpen predictions and keeps global asteroid watch efforts strong.
Apophis asteroid will pass just 32,000km from Earth
Looking ahead, India's ISRO is preparing for a much closer encounter: the Apophis asteroid will swing by just 32,000km from Earth in 2029.
ISRO plans to join worldwide projects focused on studying and maybe even deflecting risky asteroids down the line.
