A flew asteroid has its own moon

NASA published a radar observation of a 325-meter asteroid that flew past Earth on Monday at 8:19 AM Pacific Time. And it seems that asteroid 2004 BL86 has its own moon.

Asteroid 2004 BL86 flew at a distance of 3 times farther than the Earth-Moon distance (745,000 miles, or 1.2 million kilometers).

Made with a NASA 70-meter antenna in Goldstone, California, the image also shows some of the features of the asteroid.

Although there was no chance of an asteroid hitting the Earth, the 2004 BL86 deserved special attention, since the Earth will not see such an asteroid before the year 2027, when 1999 AN10 flies near the planet.

Observations made using ground-based telescopes will help scientists understand the composition of the asteroid and clarify its orbital characteristics.

According to NASA estimates, only 16 percent of asteroids are more than 200 meters in diameter or have a moon in their orbit.
