AI Thread Summary
An asteroid named "2001 FO32," the largest to pass Earth in 2021, will approach at a distance of about two million kilometers, posing no collision risk. With a diameter of less than a kilometer and traveling at 124,000 kilometers per hour, it is classified as "potentially dangerous" due to its proximity. NASA emphasizes the opportunity for scientists to study the asteroid's composition through reflected light during its close passage. Astronomy enthusiasts in certain regions may observe the asteroid with medium-sized telescopes. NASA reassures that no large asteroids are expected to collide with Earth in the next century, highlighting the importance of ongoing research to prepare for potential threats.

An asteroid that will be the largest during the year 2021 is expected to pass by about two million kilometers from Earth without the risk of colliding with it, but this astronomical event will allow scientists to study this celestial body more closely.

This asteroid is called “2001 FO32”, and its diameter is less than a kilometer, and it will pass at a speed of 124 thousand kilometers per hour, which is “faster than most asteroids” that pass near the Earth, according to the US space agency “NASA”.The agency assured that the “danger” of the asteroid colliding with the planet does not exist, as at its closest point, it will remain at a distance of more than 5 times the distance between the Earth and the Moon.

However, it remains close enough to be classified as “potentially dangerous,” according to the official categories.This asteroid was discovered in March 2001, and its trajectory has been monitored since then.

“Not much is known about this object at the present time, so its close passage gives us a great opportunity to learn a lot about it,” said Lance Penner, a scientist at NASA’s Jet Propulsion Laboratory, which belongs to him.

Researchers will be able, for example, to get a better idea of the composition of the asteroid by studying the light reflected from its surface.

“It is assumed that astronomy enthusiasts in the southern hemisphere and at low northern latitudes will be able to see this asteroid using medium-sized telescopes,” the center’s director, Paul Chodas, said in a statement.

“NASA” assured that none of the known large asteroids will hit Earth in the next century, and it is also unlikely to do those that have not been discovered yet.

But she added, “The more information we gather about these crimes, the better we can prepare to deport them in the event that one of them threatens the Earth.”

More information at https://cneos.jpl.nasa.gov/

Next closest approach will by on July 10, tomorrow, by 2021 NE (size 12-27 m) at a distance 5.78 LD (min: 5.75 LD), and followed closely on July 13, Tuesday, by 2019 AT6 (size 8-18 m) at a distance 4.22 LD (min: 3.65 LD).
See close approach data https://cneos.jpl.nasa.gov/ca/ . I expect the tabulated data are updated and replaced as asteroids move away.

According to a video by Veritasium, since 1988 more than 1200 asteroids of sizes greater than 1 m have entered the Earth and of those only 5 were detected before entering the earth. I have not independently verified the claim.
 
Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
