NASA's telescope system only detects asteroids atleast 50 meters in diameter(直径), which is just about the size of 2012DA14. But the meteor was much smaller, which made it harder to see.But what if we do see an asteroid that is headed right for the Earth?There are several possible ...
The article reports on the unveiling of the e-VLBI that creates in effect a telescope with a diameter of 11,000 kilometers by the European VLBI Network (EVN). It is stated that the VLBI increases the resolution of a pair telescopes by using the time a particular radio wave arrives at ...

The newly found interloper, called 2018 CB, is estimated to be from 50 to 130 feet (15 to 40 meters) in diameter, and will fly by Earth at about 2:30 p.m. PST (5:30 p.m. EST). "Asteroids of this size do not often approach this close to our planet — maybe only once or ...
Astronomers estimated that 2010 WC9 is around 38 to 119 meters in diameter, as big as New York City's Statue of Liberty. The asteroid was first spotted on Nov. 30, 2010, and tracked for about 10 days before astronomers failed to see it. ...
the space rock is considered a "quasi-moon" or "quasi-satellite," meaning it orbits the sun in a similar time frame as Earth does, but is only slightly influenced by our planet's gravitational pull. It is estimated to be 50 feet (15 meters) in diameter - roughly equivalent to three ...

The largest refracting telescope in the world is at the University of Chicago’s Yerkes Observatory in Wisconsin and was built in 1897. Its largest lens has a diameter of 102 cm.Around 1670, another famous scientist and mathematician — Sir Isaac Newton (1643–1727) — built a different ...
Meanwhile, Dimorphos is 525 feet (160 meters) in diameter, and its name means "two forms." Dimorphos was chosen for this mission because its size is comparable to asteroids that could pose a threat to Earth. An asteroid the size of Dimorphos could cause “regional devastation” if it ...
