Could you look at the JPL data to check this ?

They say the last closest pass of an asteroid similar in size to YU55 (well 200M) was in 1976 when Asteroid 2010 XC15 came within 0.5 lunar distance, but the JPL data does not show it came anywhere near that distance in 1976..

If you run the JPL animation backwards the closest it comes is
0.012 AU

To save you some time this happened on 25th December 1976.

or 0.012 AU = 1,115,469 miles =1,795,173 kilometers


"1976, Dec 26
Asteroid 2010 XC15 (H = 21.4 mag, D ≈ 200 m, PHA) passed Earth at 0.5 LD."

But lunar distance is 0.0024-0.0027 AU.. so why are they telling us that the 1976 asteroid 2010 XC15 came within 0.5 LD ? Which would be 0.001 AU

This grows more mysterious by the day...

Could YU55 have made a near pass in 1976 ? and the data have been altered so we can't plot it's true trajectory..
Can the super brain debunkers get on this.. hopefully I made an error, Proudbird where are you when we need you?

I believe you made an error.

Are you saying that YU55 came this close in 1976? Because if you're looking for a YU55 pass by in 1976 you won't find it.

The last time YU55 was close was about 200 years ago.

The question is, why is the data for 2010 XC15 false? Why is it being reported as the last asteroid to pass so close to the Earth in 1976.. When it didn't ? It's JPL fiction..


In effect what I am saying is 2010 XC15 and Yu55 could be the same thing..

i seam to remember a video from a few years ago of a large asteriod skimming the atmosphere, isnt that closer then 0.5 LD, and why isnt that mentioned as closest near miss?

I am seeing that the close approach data on JPL lines up perfectly with what the news is telling us..

There was indeed a close approach in 1976. I'm not sure I understand what you are trying to find?

ssd.jpl.nasa.gov...

1976-Dec-27 00:23 11:43 Earth

Nominal:
0.00202666719467948

Minimum:
0.00121525442607208

Maximum:
0.0187205381673198

1976-Dec-27 08:33 09:27 Moon

Nominal: 0.00343108595694016

Minimum: 0.00139332624781389

Maximum: 0.0212314466037635



For 2010 XC15 that is.

As it says right above it, the JPL applet is a simple 2-body simulator, so it's inaccurate over long periods of time, such as 35 years

If you look on the actual close-approach data, it lists a distance of 0.00121525442607208 AU (0.473 LD) for December 27, 1976.

Then why do they run simulations that go back to 1600 and 2200 years into the future ? If this information has no use.. What is the point in displaying the applet?

Because a 2-body simulator is accurate enough for what the average person will use the applet for - to see where in the Solar System an object is at any given time, and what its orbit looks like. But, for people who want to find the exact close-approach distance of an asteroid 35 years ago (or any other such information requiring detailed data), they provide close-approach and ephemeris data.

In February a small space rock designated 2011 CQ1 passed by earth at a distance of 3,400 miles. But it was about a meter in diameter, about the size of an exercise ball. Things like that are, well, astronomically difficult to spot out there. Here's a link, not sure if this is what you are referring to though.
