Asteroid 2026 JH2 Skims Past Earth: A “Cosmic Near Miss”

Recently, a near-Earth asteroid designated 2026 JH2 has drawn attention. It was discovered by astronomers in May 2026 and shortly afterward passed close to Earth.

According to NASA’s orbital data, 2026 JH2 came within about 90,000 kilometers of Earth at its closest approach—only about one-quarter of the Earth–Moon distance, which on a cosmic scale is considered an extremely close flyby.

This asteroid is estimated to be about 15–35 meters in diameter and belongs to the “Apollo-type near-Earth asteroids.” Its orbit crosses Earth’s orbit, so it is continuously monitored by global astronomical institutions. However, scientists have confirmed that it will not impact Earth on this pass.

Although not very large, if a similar object were to enter Earth’s atmosphere, it could still produce a powerful explosion. The 2013 Chelyabinsk meteor event in Russia is a typical example of an impact caused by an object of similar size.

Because of its close approach, 2026 JH2 became an observation target for many astronomy enthusiasts during its flyby. It also serves as a reminder that many near-Earth objects are still moving through the solar system, and continuous monitoring of them is an important step in future “planetary defense.”
