Thanks to radar observations we know that on 2004-Apr-18 23:57 ± 23 minutes #2023DZ2 passed 129,621 ± 3000 km from Earth. Yes, that is closer than the 2023 passage.

Asteroid 2023 DZ2 will pass Earth more than 100,000 miles (161,000 km) away–about half the distance to the Moon–making its close approach at 3:51 p.m. EDT (12:51 p.m. PDT). Check out @nasa_eyes on Asteroids at https://eyes.nasa.gov/apps/asteroids/#/asteroids/2023_dz2

In 10 minutes asteroid #2023DZ2 - https://skyweek.wordpress.com/2023/03/15/allgemeines-live-blog-ab-dem-15-marz-2023/ - will be closest to Earth: https://twitter.com/NASA/status/1639694231403995137 (the asteroid should have reached 10th magnitude today - but I couldn't care less because in Europe it only rises tomorrow morning when already down to 11th or 12th mag. and will be poorly placed in the sky anyway).

#Asteroid #2023DZ2 diameter 160ft/50m may sound familiar. It's the same as the estimated size of the impactor that created Meteor Crater in Arizona. Crater 0.75mi/1.2km wide, like a stadium for 2 million people. (My pic Dec 2010) #astronomy #geology #LowFlyingRocks

With asteroid 2023 DZ2 about to fly by Earth the DSN is involved in data gathering with the big Goldstone 70M antenna and its 500kw solar system radar and currently Canberra's DSS34 and 35 with their little 20kw transmitters. @CSIRO_ATNF and @UTAS_ antenna will receive the bounce

Both ~60-meter Near-Earth #Asteroids with possible impacts this century, #2023DW and #2023DZ2, have now been removed - thanks to further astrometry - from the risk list: https://cneos.jpl.nasa.gov/sentry/removed.html

#2023DW is now off the impact hazard list entirely: https://cneos.jpl.nasa.gov/sentry/removed.html .

#2023DZ2 is down to impact probability 1:38,000,000 in the foreseeable future and will be removed from the hazard list soon.

Again: This happens all the time.

Asteroid folks:

Has anyone reported observations of #2023DW or #2023DZ2 other than astrometry?

I have not yet found reports of lightcurves or spectra.

The impact probability of #asteroid #2023DZ2 (in 2026) has now shrunk to one in 71,000 or one in 530,000 according to further calculations by JPL and ESA, respectively, using astrometry from 14 January til today. (And #2023DW has no longer any chance to collide with Earth in 2046).

With today's orbit update; the impact probability for #2023DW is down to one potential impact in 2049 with probability 1:22,000,000 that has not yet been ruled out.

#2023DZ2 is down to 1:71,000.

An erroneous "all clear" for #asteroid #2023DZ2 has been retracted (in a personal mail from the originator): with an observational arc from Jan. 14 to March 18 P_impact (2026) is now 1 in 430, according to https://cneos.jpl.nasa.gov/sentry/details.html#?des=2023%20DZ2. Whatever its plans, the asteroid will be an interesting #sky object a week from now: https://earthsky.org/space/200-ft-asteroid-2023-dz2-will-pass-by-earth-closer-than-the-moon/ - according to my calculations with https://ssd.jpl.nasa.gov/horizons/app.html the asteroid will be ninth magnitude in Virgo for three hours around 17:00 UTC on 25 March 2023.

Newly-discovered asteroid 2023 DZ2 will pass less than half the Moon's distance on March 25. Dozens of meters wide, it will get as bright as magnitude 9.7, putting it in the range of binoculars. It currently has a 1/550 chance of impacting Earth 3 years later in 2026. #2023DZ2
