A newly discovered asteroid, known as 2018 MB7, is expected to fly by Earth on Wednesday, July 4, at around 8:38 UTC. The space rock will miss our planet with a relative velocity of 11.6 km/s at a distance of about 2.78 lunar distances (LD), what corresponds to 1.07 million kilometers.

2018 MB7 is an Apollo-type asteroid detected June 21, 2018 by the Mount Lemmon Survey (MLS). MLS utilizes a 1.52 m cassegrain reflector telescope at Mount Lemmon Observatory in Arizona. It is one of the most prolific surveys when it comes to discovering new near-Earth objects (NEOs). So far, it has detected more than 50,000 minor planets.

According to astronomers, 2018 MB7 has an absolute magnitude of 23.8. The object orbits the Sun every 539 days at a distance of about 1.3 AU from it.

About one hour after Wednesday’s fly-by of Earth, 2018 MB7 will also pass by the Moon at a distance of 2.62 LD (1.01 million kilometers).

Next close approach of this asteroid to Earth will occur on December 19, 2018, at a much larger distance of about 158 LD (60.6 million kilometers).

On July 1, there were nearly 2,000 potentially hazardous asteroids (PHAs) detected, however none of them is on a collision course with our planet. PHAs are asteroids larger than 100 meters that can come closer to Earth than 19.5 LD.

To date, astronomers have discovered more than 18,400 NEOs. Since the beginning of this year, 886 such objects have been detected.
