Asteroid 2005 YU55
Medienspektakel, zu sehen ist aber nichts
In der Nacht vom 8. auf den 9. November 2011 fliegt der kleine Asteroid mit der Bezeichnung 2005 YU55 an der Erde vorbei und kommt dabei näher als der Mond. Eine Kollision ist nicht zu befürchten, zu sehen wird es ohne Fernrohr aber nichts geben - das kleine Objekt ist viel zu lichtschwach.
Der rund 400 Meter kleine Asteroid mit der offiziellen Bezeichnung 2005 YU55 wird am 9. November 2011 der Erde näher kommen als der Mond. Um Mitternacht (Nacht vom 8. auf den 9. November) wird die Entfernung des Asteroiden von der Erde rund 324.000 Kilometer betragen.
Der Asteroid umkreist die Sonne einmal in eineinviertel Jahren auf einer elliptischen Bahn. In Sonnenferne erreicht er gerade die Marsbahn, in Sonnennähe steht er etwas innerhalb der Venusbahn.

2005 YU55 ist ein so genannter Erdbahnkreuzer. Seine Bahn ist kaum zur Erdbahn geneigt und so kommt der kleine Himmelskörper unserem Planeten immer wieder sehr nahe.

Am 9. November 2011 kommt es an einer der beiden Stellen, an denen sich die Bahnen von Asteroid und Erde sehr nahe kommen, zu einer engen Begegnung.

Zu einer Kollision der beiden Himmelskörper kann es aufgrund der Bahnlage zum Glück nicht kommen! Das Ereignis sorgt zwar für erhebliches Medienecho, sehen wird man allerdings ohne Fernrohr nichts. Selbst zum Zeitpunkt der größten Annäherung an die Erde wird der kleine Asteroid so lichtschwach sein, dass er nur mit einem größeren Fernrohr gesehen werden kann.
Für interessierte Beobachter hier noch Bahnelemente und Ephemeride für Wien, erstellt mit dem JPL Horizons System; sie zeigt deutlich, dass 2005 YU55 von Wien aus in seinem Vorbeiflug an der Erde praktisch nicht beobachtbar ist. Der Asteroid geht bereits nach 22 Uhr MEZ unter und ist da noch schwächer als 13 mag.

Column meaning:
TIME
Prior to 1962, times are UT1. Dates thereafter are UTC. Any 'b' symbol in
the 1st-column denotes a B.C. date. First-column blank (" ") denotes an A.D.
date. Calendar dates prior to 1582-Oct-15 are in the Julian calendar system.
Later calendar dates are in the Gregorian system.
The uniform Coordinate Time scale is used internally. Conversion between
CT and the selected non-uniform UT output scale has not been determined for
UTC times after the next July or January 1st. The last known leap-second
is used over any future interval.
NOTE: "n.a." in output means quantity "not available" at the print-time.
SOLAR PRESENCE (OBSERVING SITE)
Time tag is followed by a blank, then a solar-presence symbol:
'*' Daylight (refracted solar upper-limb on or above apparent horizon)
'C' Civil twilight/dawn
'N' Nautical twilight/dawn
'A' Astronomical twilight/dawn
' ' Night OR geocentric ephemeris
LUNAR PRESENCE WITH TARGET RISE/TRANSIT/SET MARKER (OBSERVING SITE)
The solar-presence symbol is immediately followed by another marker symbol:
'm' Refracted upper-limb of Moon on or above apparent horizon
' ' Refracted upper-limb of Moon below apparent horizon OR geocentric
'r' Rise (target body on or above cut-off RTS elevation)
't' Transit (target body at or past local maximum RTS elevation)
's' Set (target body on or below cut-off RTS elevation)
RTS MARKERS (TVH)
Rise and set are with respect to the reference ellipsoid true visual horizon
defined by the elevation cut-off angle. Horizon dip and yellow-light refraction
(Earth only) are considered. Accuracy is < or = to twice the requested search
step-size.
R.A._(ICRF/J2000.0)_DEC =
J2000.0 astrometric right ascension and declination of target center.
Corrected for light-time. Units: HMS (HH MM SS.ff) and DMS (DD MM SS.f)
R.A._(a-apparent)__DEC. =
Airless apparent right ascension and declination of the target center with
respect to the Earth true-equator and the meridian containing the Earth true
equinox of date. Corrected for light-time, gravitational deflection of light,
stellar aberration, precession & nutation.
Units: HMS (HH MM SS.ff) and DMS (DD MM SS.f)
Azi_(a-appr)_Elev =
Airless apparent azimuth and elevation of target center. Corrected for
light-time, the gravitational deflection of light, stellar aberration,
precession and nutation. Azimuth measured North(0) -> East(90) -> South(180) ->
West(270) -> North (360). Elevation is with respect to plane perpendicular
to local zenith direction. TOPOCENTRIC ONLY. Units: DEGREES
APmag S-brt =
Asteroid's approximate apparent visual magnitude & surface brightness:
APmag = H + 5*log10(delta) + 5*log10(r) - 2.5*log10((1-G)*phi1 + G*phi2)
In principle, accurate to ~ +/- 0.1 magnitude. For solar phase angles > 90 deg,
the error could exceed 1 magnitude. No values are output for phase angles
greater than 120 degrees, since the errors could be large and unknown.
Units: NONE & VISUAL MAGNITUDES PER SQUARE ARCSECOND
delta deldot =
Range ("delta") and range-rate ("delta-dot") of target center with respect
to the observer at the instant light seen by the observer at print-time would
have left the target center (print-time minus down-leg light-time); the
distance traveled by a light ray emanating from the center of the target and
recorded by the observer at print-time. "deldot" is a projection of the
velocity vector along this ray, the light-time-corrected line-of-sight from the
coordinate center, and indicates relative motion. A positive "deldot" means the
target center is moving away from the observer (coordinate center). A negative
"deldot" means the target center is moving toward the observer.
Units: AU and KM/S
Cnst =
Constellation ID; the 3-letter abbreviation for the name of the
constellation containing the target center's astrometric position,
as defined by IAU (1930) boundary delineation. See documentation
for list of abbreviations.

Ein Beobachtungstipp der WAA Wenn Sie Anleitungen oder Hilfestellungen dazu benötigen, dann sind Sie bei unseren gemeinsamen Beobachtungen herzlich willkommen. Bitte schauen Sie regelmäßig auf unsere Homepage oder kontaktieren Sie unsere Hotline 0664/256-1221 bezüglich eines Termins. Achtung, aufgrund der in unserer Region stets unsicheren Wetterlage können wir diese Termine meist erst am Tag der Beobachtung festlegen. |
