Before handling NASA's planetary defense, Johnson was the Near-Earth Object
Programs Executive for NASA's Planetary Sciences Division.
Asteroid 2000 QW7, a near-Earth object
, will fly by at a safe distance of 5.3 million km at a speed of 23,100 kmph, according to NASA's Center for Near Earth Object Studies (CNEOS), a part of the Jet Propulsion Laboratory in Pasadena, California, the Indian Express reported.
Summary: TEHRAN (FNA)- Researchers are using the Catalina Sky Survey's near-Earth object
telescopes to locate the optical counterparts to gravitational waves triggered by massive mergers.
Data from the Centre of Near-Earth Object
Studies (CNEOS) tells us that it will fly by Earth once again around July 7, 2119.

Camera would operate as an observatory in space to detect objects that may collide with Earth.
4), Peter Tyson refers to the newly discovered interstellar visitor 'Oumuamua as a "near-Earth object
." This seems reasonable, as this asteroidal object's perihelion was 0.255 astronomical unit (on September 9, 2017), and the official definition of NEOs is "asteroids and comets with perihelion distance q less than 1.3 au" (cneos.jpl.nasa.gov/ about/neo_groups.html).
"Asteroids of this size do not often approach this close to our planet -- maybe only once or twice a year," said Paul Chodas, manager of the Center for Near-Earth Object
Studies at NASA's Jet Propulsion Laboratory in California.

Studies manager Paul Chodas noted, 'So far, everything indicates this is likely an interstellar object, but more data would help to confirm it.' JB
At first he thought it was a type of space rock known as a near-Earth object
, but he realised its motion did not make sense.
JPL manages and operates NASA's Deep Space Network, including the Goldstone Solar System Radar, and hosts the Center for Near-Earth Object
Studies for NASA's Near-Earth Object
Observations Program, an element of the Planetary Defense Coordination Office within the agency's Science Mission Directorate.
A more direct attempt to defend against asteroids is a joint European Space Agency-NASA program, the "asteroid impact and deflection assessment mission." It has actually identified a rock called 65803 Didymous that will be close enough to Earth in October 2022 to test the ability to move a near-Earth object
into a different trajectory.
