the MOID is a LOT closer than that now. |

''minimum orbit intersection distance'' Quoting: Anonymous Coward 357098
@ 0.8 LD = < 1 Lunar Distance
Meaning the object could come closer to earth than our moon. |

this only states how close the object will be to our orbital path
it does not state that we will be there when it does this |

Anonymous Coward User ID: 177315 1/17/2008 2:22 PM | | Re: ASTEROID TU24 EARTH MOID NOW @ 0.8 LD | Quote | I believe LD means lunar distance.....
so .8LD would be about 191,000 miles. |

chill out baby, we know that.
have a cup of tea and chill.
Anyway, it's not KNOWN rocks like this we need to worry about. it's the ones WE know fuck all about. |

It means that the trajectory is inside the orbital distance of the moon, which is 230,000 miles.
The slightest deviation of the projected tragectory, like for instance the effects of the gravitational attraction of the moon on the asteroid, could result in an Earth impact.
COULD, not will. |

If you run JPLS program an hour at a time on the 28th you see that the distance to Earth changes ~.00002 AU per hour. However on the 29th it changes ~.00001 AU per hour and starting at 0900 hrs it stays at .00038AU untill 1500 hrs. What di it do for six hours stop? You know how far that thing travels in six hours and they have it stopping????

The roid's orbit and the earth's orbit syncronize for a few hours in that the roid remains at about the same distance, just moves laterally.. like the moon does, except at a much smaller scale |

Anonymous Coward User ID: 177315 1/17/2008 3:12 PM | | Re: ASTEROID TU24 EARTH MOID NOW @ 0.8 LD | Quote | 2007 TU24 was discovered by the Catalina Sky Survey (Arizona) on October 11, 2007.
This object's 1.4-lunar-distance approach on Jan. 29 is the closest for any
known Potentially Hazardous Asteroid until 2027. At this writing, the
object's orbit is too uncertain to identify post-2008 close Earth
approaches, but radar astrometry probably may allow prediction of any
close approaches centuries into the future.
Apart from its absolute visual magnitude (H = 20.1, implying a
diameter ~0.3 km if it has a typical S-class albedo), nothing is known
about TU24's physical properties, but the expected echo
signal-to-noise ratios (SNRs) almost certainly will suffice for
high-resolution using Arecibo or Goldstone.
Goldstone observations are scheduled on January 23 and Arecibo observations are
scheduled on January 27-28 and February 1-4. Note that Goldstone observations straddle
the January 23-24 date boundary.
This object will brighten to about 11th magnitude in late January
when it will be a target for photometric and spectroscopic observations.
Orbital and Physical Characteristics
orbit type Apollo
semimajor axis 2.010 AU
eccentricity 0.529
inclination 5.8°
perihelion distance 0.947 AU
aphelion distance 3.073 AU
absolute magnitude (H) 20.1
diameter 300 meters +- a factor of two
rotation period unknown
pole direction unknown
lightcurve amplitude unknown
spectral class unknown

I see it's closest approach as .0038 AU....about a half a million miles...give or take....not .0003AU....
that puts it outside the moons orbit if correct. |
