Asteroid 39 Laetitia will probably be effectively positioned,
mendacity within the constellation Cetus, effectively above the
horizon for a lot of the evening.
No matter your location on the Earth, 39 Laetitia will attain its
highest level within the sky round midnight native time.
From Los Angeles, will probably be seen between 20:58 and 04:57. It would turn out to be accessible at round 20:58, when it rises to an altitude of 21° above your jap horizon. It would attain its highest level within the sky at 00:58, 51° above your southern horizon. It would turn out to be inaccessible at round 04:57 when it sinks beneath 21° above your western horizon.
The geometry of the alignment
This optimum positioning happens when it makes its closest method to the purpose
within the sky immediately reverse to the Solar – an occasion termed
opposition. Because the Solar reaches its best distance beneath the
horizon at midnight, the purpose reverse to it’s highest within the sky on the identical
time.
At across the identical time that 39 Laetitia passes opposition, it additionally
makes its closest method to the Earth – termed its perigee
– making it seem at its brightest within the evening sky. This occurs
as a result of when 39 Laetitia lies reverse to the Solar within the evening sky, the
photo voltaic system is lined up in order that 39 Laetitia, the Earth and the Solar lie
in a straight line with the Earth within the center, on the identical facet of the Solar
as 39 Laetitia.
On this event, 39 Laetitia will cross inside
1.479 AU of us, reaching a peak brightness of
magnitude 9.2.
Nonetheless,
even at its brightest, 39 Laetitia is a faint object past the attain of
the bare eye; binoculars or a telescope of average aperture are wanted.

The place of 39 Laetitia in the mean time of opposition will probably be as follows:
| Object | Proper Ascension | Declination | Constellation | Magnitude |
| Asteroid 39 Laetitia | 01h10m50s | 3°59’S | Cetus | 9.2 |

The circumstances of this occasion have been computed from
orbital components
made accessible by Ted Bowell of the Lowell Observatory. The conversion to geocentric coordinates was carried out utilizing
the place of the Earth recorded within the
DE430
ephemeris printed by the Jet Propulsion Laboratory (JPL).
The star chart above exhibits the positions and
magnitudes
of stars as they seem within the
Tycho catalogue.
The info was diminished by the creator and plotted utilizing
PyXPlot. A gnomonic
projection of the sky has been used; celestial coordinates are indicated in
the J2000.0 coordinate system.
