CRT 2005 Object Archive

for objects that appeared on the CRT page during 2005
but no longer have impact solutions or are not presently under active observation
and aren't yet in, or updated fully in, A/CC's Catchall Catalog of Minor Objects

Note: All objects listed with impact solutions from March 2002 through 2005 JO3 in early May 2005 can be found in A/CC's Catchall Catalog version 4 and version 3 (version 4 has 285,500-plus listings, and has more functionality, but isn't available on A/CC's backup site, and may suffer the occasional hiccup).
      This CRT 2005 Object Archive page was begun on 8 Oct. 2005 as a temporary repository to keep info available to readers while decreasing CRT page download size. Earlier listings that belong here are being recalled from A/CC's records and added as time permits, going back to May 2005. The plan is to later move all of these into the Catchall, when the substantial time needed for that update becomes available.

2005 YU55

Current assessments:  NEODyS [backup] & JPL NEOPO

Diameter:  138 meters (JPL 10 Jan. 2006 estimate)

JPL:  Orbit Viewer     NEODyS:  object home page [backup] & observations [backup]

Circulars:  MPEC 2005-Y47

Notes:  2005 YU55 was discovered with the Spacewatch 0.9m telescope on 28 Dec. 2005 and, after confirmation overnight, was announced the next day. This is when JPL posted it with 1,111 highly-preliminary impact solutions beginning in early 2009, which changed to 111 solutions starting in 2028 when the next observations became available. NEODyS posted it on Dec. 31st.

On Jan. 5th it was reported that this object was observed on 30 and 31 Dec. and 4 and 5 Jan. JPL posted its updated risk assessment on the 6th UTC (still the 5th local time), cutting its solution count by a tenth, to 111, with the earliest in 2028.

NEODyS in February called this object "lost" but notes "possible recovery in December 2006."

2005 XA8

Current assessments:  NEODyS [backup] & JPL NEOPO

Diameter:  30 meters (JPL 28 Dec. 2005 estimate)

JPL:  Orbit Viewer     NEODyS:  object home page [backup] & observations [backup]

Circulars:  MPEC 2005-X40

Notes:  2005 XA8 flew through the Earth-Moon system at 0.6 lunar distance on 5 Dec. 2005 and two days later was discovered by LINEAR, which actually had picked it up on the 6th. The discovery was announced on the 8th, which is when JPL and NEODyS posted it with impact solutions.

This object went technically out of view for most NEO observers on Dec. 22nd.

On 14 Jan. 2006, NEODyS revised its risk assessment, removing all impact solutions.

At absolute magnitude H=25.5 reported by JPL on Dec. 9th, 2005 XA8 is among the largest objects to be observed by telescope passing so close, although certainly less bright than the closer-passing 2002 MN's H=23.2 (a size difference that works out very roughly to 25 vs. 75 meters).

2005 WY55

Current assessment:  NO impact solutions

Diameter:  250 meters (JPL 25 Feb. 2006 estimate)

JPL:  Orbit Viewer     NEODyS:  object home page [backup] & observations [backup]

Circulars:  MPEC 2005-W91

Notes:  2005 WY55 was discovered on 26 Nov. 2005 and announced on the 30th UT, which is when JPL and NEODyS posted it with impact solutions.

The Spaceguard Central Node's observing campaign's first page from April to June 2006 said about 2005 WY55, "easy to observe with a large telescope from March to July," but no observations after mid-January were reported until June 27th. On July 1st observations were published from the Nordic Near-Earth-Object Network (NEON) using the 2.5m Nordic Optical Telescope on La Palma in the Canary Islands, adding 166.996 days to what had been a 45.747-day observing arc. And on July 1st NEODyS and JPL removed 2005 WY55 as an impact risk.

2005 WY

Current assessment:  NO impact solutions

Diameter:  10 meters (23 Nov. 2005 estimate from standard formula)

JPL:  Orbit Viewer     NEODyS:  object home page [backup] & observations [backup]

Circulars:  MPEC 2005-39

Notes:  2005 WY was discovered with the Spacewatch 0.9m telescope on 21 Nov. 2005, announced the next day. NEODyS posted it as an impact risk on the 23rd removed it on the 27th. This object passed Earth on Nov. 27th at 2.0 lunar distances, and is estimated to be on the order of ten meters wide.

2005 WN3

Current assessments:  NEODyS [backup] & JPL NEOPO

Diameter:  4 meters (JPL 9 Jan. 2006 estimate)

JPL:  Orbit Viewer     NEODyS:  object home page [backup] & observations [backup]

Circulars:  MPEC 2005-W65

Notes:  2005 WN3 was discovered on 25 Nov. 2005 by the Mt. Lemmon Survey about 17 hours before this tiny object buzzed the Earth at 22% of the distance to the Moon and then went out of view. This was announced on 26th, which is when JPL posted it with one very low-rated impact solution. NEODyS posted it the next day.

2005 WN3's orbit-changing passage through the Earth-Moon system a half-hour into 26 Nov. UT, as calculated from observations spanning only 12.26 hours, is believed to be the closest observed so far in 2005 and the fifth closest ever caught by telescope.

Circulars:  MPEC 2005-T61

Notes:  2005 TU45 was discovered on 5 Oct. 2005 with the 3.6m Canada-France-Hawaii Telescope (CFHT) on Mauna Kea in Hawaii and was announced on Oct. 10th, which is when JPL posted it with impact solutions. NEODyS posted it the next day.

CFHT discovery and follow-up credits are combined in the MPEC as "Observers P. Forshay, J. Luthe. Measurers A. Boattini, F. Bernardi." David Tholen tells A/CC on 11 Oct. that "2005 TU45 is another one of our small solar elongation discoveries using queue time at CFHT."

This object technically went out of view for most NEO observers on Nov. 30th. JPL and NEODyS removed it as a risk on 2 March 2006 when observations became available from Tholen et al. from 11-12 Nov.
