Astronomer Scott Sheppard of the Carnegie Institution for Science in Washington DC states that the discoveries of near-Earth objects (NEO) they are still waking up. This is because telescopes tend to look away from our planet to avoid the sun’s glare; however, new surveys are revealing asteroids hidden by our star’s glare, objects never seen before.
The researchers claim that finding and tracking these space rocks could be vital to help improve our understanding of planet formation and the history of the solar system.
“New telescopic surveys are challenging the sun’s glare and searching for sunward asteroids at twilight,” Sheppard wrote in the journal Science. “These surveys have found many previously undiscovered asteroids around Earth.”
Many go unnoticed
Thus, potentially dangerous rocky objects they could be hidden in the light of our star. We have a blind spot. The biggest asteroid discoveries are being made at twilight, when astronomers can look near the horizon, and near the sun, for little-known asteroids orbiting within the orbits of Earth, Venus, and even Mercury.
The sky is cloudy just after sunset or just before sunrise, but bright enough to make searching difficult. But defying the twilight, asteroid hunters have been able to find many asteroids that cross the Earth’s orbit and some circulate in the inner solar system.
Precisely by observing at twilight, scientists working with the Victor M. Blanco telescope four meters in Chile they found the first known asteroid that orbits closer to the Sun than Venus and the largest potentially dangerous asteroid for the Earth that has been found in recent years. Models had predicted that these space rocks should exist, but now telescopes they are beginning to confirm their presence.
