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.

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.
