NASA astronomers have recently captured radar images of asteroid 2013 NK4 using the Goldstone Radar in California. The images reveal that the asteroid is likely a binary contact, consisting of two bodies that have come together, resulting in its elongated shape.
Measuring about 2,000 feet in diameter, asteroid 2013 NK4 is twice as large as the infamous doomsday asteroid Apophis. The closest approach of the asteroid occurred on April 15, 2024, at 14:51 UTC. Although the asteroid’s orbit is well-defined, it does occasionally pass near Earth, earning it the classification of a Potentially Hazardous Asteroid.
NASA astronomers are currently studying asteroid 2013 NK4 using radar antennas in California and Australia until April 19. While the asteroid can be observed through a telescope as a slowly moving point of light against the background stars, it passed Earth at a safe distance, more than 8 times the moon’s distance at its closest point.
With an orbit around the sun every 378 days, asteroid 2013 NK4 follows a slightly more elliptical path than Earth. Those with telescopes can catch a glimpse of the asteroid on the nights of April 16 and 17. NASA anticipates obtaining detailed images of the asteroid’s shape and size through their radar observations.
This event serves as a reminder of the importance of ongoing astronomical research and monitoring for potentially hazardous space objects. While asteroid 2013 NK4 poses no immediate threat, continued observation and study are crucial for understanding and preparing for potential future encounters with such celestial bodies.
