The night sky often feels calm and endless. Yet, sometimes a space rock appears and captures global attention. This week, asteroid 2025 QH16 takes the spotlight.

How close will asteroid 2025 QH16 come?
NASA confirmed the asteroid is on a safe path. The rock measures about 43 feet in width. It is travelling at 18,583 miles per hour. On 2 September, it will pass Earth quietly. Its closest distance will be 2,810,000 miles away. Astronomers say this is close by space standards. The asteroid belongs to the Aten group, which often crosses Earth’s orbit. Despite the attention, experts stress it poses no danger.

Why is the asteroid not considered hazardous?
NASA defines hazardous rocks using size and distance. Only objects wider than 85 metres are tracked closely. Distance also matters if they come within 7.4 million kilometres. Asteroid 2025 QH16 does not meet those standards. Scientists confirm it is safe and will not threaten Earth. Still, they highlight the importance of tracking such flybys.

Why do space agencies track even harmless flybys?
Even slight orbital shifts could alter a rock’s path. That is why agencies maintain global watch on asteroids. Regular monitoring ensures readiness for unexpected movements. ISRO Chairman S. Somanath recently shared new goals. He plans to study large objects like Apophis in 2029. Collaboration with NASA, ESA, and JAXA is also planned. India is preparing to land missions on future asteroids.

Though safe, the flyby reminds us of cosmic surprises. A calm night sky can quickly change with visitors. The passage highlights the importance of continued research and vigilance. While 2025 QH16 will pass without harm, scientists remain watchful.
