A newly identified near-Earth asteroid known as 2026 JH2 will pass remarkably close to Earth on May 18, 2026. Despite the dramatic proximity, scientists say there is no indication that the space rock poses any danger to the planet.
The object was spotted only a few days ago by astronomers working with several observatories, including the Mount Lemmon Survey and the Farpoint Observatory in Eskridge, Kansas. Since its discovery, researchers have been tracking its orbit closely as the celestial object approaches the Earth-Moon system.
Near-Earth asteroids are monitored continuously because some objects can pass relatively close to the planet. In this case, preliminary orbital calculations classify 2026 JH2 as an Apollo-class near-Earth object, meaning its orbit crosses Earth’s path around the Sun.
The Asteroid Will First Pass Close To The Moon
Before reaching its closest point to Earth, 2026 JH2 will make a near approach to the Moon. Data released after the asteroid’s detection indicate that the encounter is expected around 6:51 pm UTC on Monday, May 18, although astronomers noted there remains an uncertainty margin of roughly five hours due to the limited amount of tracking data currently available.
The asteroid is predicted to come within 0.00284 astronomical units of the Moon. One astronomical unit, commonly abbreviated as AU, corresponds to the average distance between Earth and the Sun.
Researchers explained that the orbit could still be refined as additional observations are collected. Newly discovered asteroids often require repeated measurements before scientists can determine their exact speed, size, and orbital path with precision.
As reported by observatories monitoring the object, astronomers around the world and automated sky surveys continue tracking it as it moves through near-Earth space.
Earth Flyby Expected Just Hours Later
After passing the Moon, the asteroid will continue toward Earth and reach its closest approach later that evening. Current calculations place the event at approximately 9:23 pm UTC. Published estimates show that 2026 JH2 is expected to pass within 0.00064 astronomical units of Earth at maximum, with some calculations placing the minimum distance at 0.00058 AU. As mentioned by Forbes, while those numbers may appear alarming at first glance, the asteroid will still remain around 90,000 kilometers, or roughly 56,000 miles, from Earth.
Scientists involved in tracking the encounter stressed that there is no suggestion of an impact with the planet. The distance corresponds to about 24 percent of the average distance between Earth and the Moon, making it close in astronomical terms while still remaining safely beyond Earth’s atmosphere.
The asteroid’s proximity has nevertheless drawn attention because encounters at such distances are relatively uncommon, particularly for objects discovered only shortly before their flyby.
Amateur Observers May Be Able To See The Object
The close approach is also expected to make the asteroid visible with relatively modest observing equipment. The Virtual Telescope Projectestimates that the asteroid could brighten to around magnitude 11.5, placing it within reach of many amateur telescopes under favorable sky conditions.
The organization also announced plans to livestream observations of the flyby beginning at 7:45 pm UTC on May 18. The broadcast should allow viewers without telescopes or clear skies to follow the event remotely.
Astronomers frequently rely on public observations during events like these, especially when an asteroid has only recently been discovered. The additional data collected during close passes can help improve orbital calculations and reduce uncertainties surrounding an object’s trajectory.
