Astronomers are vigilantly scanning the skies for asteroids that veer into Earth’s solar system neighborhood. However, some are hidden. Most asteroids — leftover rubble from our photo voltaic system’s formation some 4.6 billion years in the past — orbit the solar between Mars and Jupiter. Tens of millions exist on the market. However within the internal photo voltaic system, asteroids are obscured by the blinding glare from the solar. Now, a brand new survey of house rocks in areas across the orbits of Venus and Mercury have noticed sizable asteroids on this elusive zone of space. One is almost a mile large, the kind of “planet-killer” rock that may decimate life on Earth. Fortuitously, these rocks don’t currently pose any danger to our planet, nor will they for the foreseeable future — although over centuries, or for much longer, one of many asteroids’ orbits could change and probably pose a menace.
