A large asteroid, designated 1997 NC1, will pass Earth at a safe distance of 1.5 million miles (2.4 million kilometers) on June 27, 2026. Measuring approximately 0.6 miles (1 kilometer) wide, this Aten-type asteroid is categorized as a Potentially Hazardous Asteroid due to its size and proximity to Earth’s orbit. According to the Near-Earth Asteroid Tracking system, the object poses no danger of impact during this flyby.
How does 1997 NC1 compare to past asteroid events?
The 1997 NC1 flyby is significantly different from the 2013 Chelyabinsk meteor event. While the Chelyabinsk meteor was roughly 60 times smaller than 1997 NC1, it caused widespread damage because it entered the atmosphere directly. According to data provided by the Near-Earth Asteroid Tracking system, 1997 NC1 will remain nearly seven times further away than the moon, whereas the Chelyabinsk object struck the atmosphere directly above Russia. A more recent point of comparison is asteroid 1994 PC1, which passed Earth in January 2022 at a distance of 1.23 million miles—slightly closer than the upcoming 1997 NC1 encounter.
Why is radar imaging critical for asteroid research?
Radar imaging allows scientists to determine an asteroid’s precise shape, size, and composition, moving beyond simple optical observations. Lance A. M. Benner, an asteroid expert at NASA/JPL, notes that radar signals can reveal whether an object is a solid boulder or a “rubble pile.” For the 1997 NC1 flyby, astronomers plan to utilize the 34-meter DSS-26 and DSS-13 antennas at the Goldstone Deep Space Communications Complex to collect data. These observations are intended to calibrate existing measurements from the Spitzer Space Telescope and the NEOWISE spacecraft.
What are the current limitations in tracking large asteroids?
The global capacity for deep-space radar imaging has diminished following the 2020 collapse of the Arecibo Observatory in Puerto Rico. According to NASA/JPL’s Lance A. M. Benner, the loss of the 1,000-foot Arecibo dish, combined with the fact that the 70-meter DSS-14 dish at Goldstone is offline for modernization until 2028, has left researchers with fewer high-resolution tools. Consequently, astronomers are currently relying on smaller antenna arrays in California and Australia to study medium-to-large near-Earth objects.
Frequently Asked Questions
- Is asteroid 1997 NC1 going to hit Earth? No. It will pass at a distance of 1.5 million miles, which is nearly seven times the distance to the moon.
- Can I see the asteroid without a telescope? No. It is not visible to the naked eye. Observers require a telescope with an aperture of at least 6 inches (15 cm).
- Why is it called a “Potentially Hazardous Asteroid”? The classification is based strictly on its size and the fact that its orbit brings it relatively close to Earth, not because of any specific threat of impact.
- What would happen if an asteroid this size hit Earth? According to impact models, a 1-kilometer asteroid would likely punch through the atmosphere, strike the surface at 20,000 mph, and create a crater up to 9 miles wide, potentially triggering a global food crisis.
