A few thousand NEOs have been identified by astronomers, including asteroids, meteroids, comets, and even some human-made objects.
The new asteroid is about 4 kilometers in diameter. When discovered by Todd, it had an apparent magnitude of about 19.5 and was about 125 to 400 million kilometers from Earth.
It is so dim that it shines several thousandth times fainter than the faintest stars visible to the unaided eye.
In fact, according to the ScienceAlert.com article “Sky search finds big asteroid,” David Coward, the Zadko Telescope project leader, stated, “To put this in perspective, the asteroid image obtained by the Zadko Telescope is the same as detecting a grain of sand from 130 km away.”
Many more of these tiny NEOs have been detected recently as our instruments and telescopes increase in size and accuracy.
Dr. Coward states, “In the next 6 months Mick plans to search for asteroids and rocks lurking closer to Earth. Some of these are so close that impacts can occur only hours after discovery.”
