I just wanted an expert opinion on how close this encounter would be, as i have no idea what AU is, i just came across it while watching the animations on the NASA website.

I don't know, but you could probably Google AU and get your answer.

The moon is 0.0025AU (Roughly) away from the earth.

That should give a bit of perspective.

Im not an expert but lately ive taken interest in similar topics to this.

AU- neo.jpl.nasa.gov...


Well that puts it in even better perspective

1 Au = the distance from earth to the sun.

1 AU is approxomitely the distance between the earth and sun about 93 million miles if memory serves.

Hey this was news to me too....

Definition: An Astronomical Unit is approximately the mean distance between the Earth and the Sun. It is a derived constant and used to indicate distances within the solar system. Its formal definition is the radius of an unperturbed circular orbit a massless body would revolve about the sun in 2*(pi)/k days (i.e., 365.2568983.... days), where k is defined as the Gaussian constant exactly equal to 0.01720209895. Since an AU is based on radius of a circular orbit, one AU is actually slightly less than the average distance between the Earth and the Sun (approximately 150 million km or 93 million miles


Ahhh another word for the day from ATS, I luvz my ats edumucationing

553,512 kilometres.

Roughly. Or....

343,936 miles if you are that way inclined.

= 149,668,992 kilometers or 93 million miles actually.

AU is the distance between Earth and the Sun which I think is around 93-96 million miles..so 2 Au's would be 186 million miles..and so forth..

Nope, well yes if you mean 1 AU but the OP was talking about .0037AU.
I think.

I will do the math here for everyone:

1 AU = 1 astromical unit = the distance from the earth to the sun = 93,000,000 miles aprox

.0037 AU = the distance of the near earth object in the OP

93,000,000 x .0037 = 344,100 miles away

the moon is on average approx 384,000 miles from earth so this obect is just closer to us than the moon is.

or will be in the year 2060

0.0037 au from earth to object, could the earth suck it in from that distance?

It's close but there has been closer, according to this graphic at least one and others around the mark. We have been fine so far. Think of all the ones we have missed in the passed. The closest has a 1 in 10million chance it could return and hit us next time round so I would guess those numbers will rise. Basically .0037 is further out than the Moon.
Sorry it's a bit small.

neo.jpl.nasa.gov...

According to that, there is/was a 0.0021 AU NEO today- not sure if it's passed yet. Only estimated to be 8 metres in size, though. When I searched for it on google, I saw a thread someone on godlikeproductions had created, thinking it was 8 miles wide and was panicking

easy mistake I guess, if you dont know that NASA uses the metric system haha
Not everyone does their research i'm afriad.

Moon is about, roughly, 250,000 miles form earth. The object in question, is outside the orbit of the moon, and probably traveling too fast to be captured by earths gravity. Wouldnt worry about it
