Asteroid 1036 Ganymed will be well placed, lying in the constellation Pegasus, well above the horizon for much of the night.

Regardless of your location on the Earth, 1036 Ganymed will reach its highest point in the sky around midnight local time.

From Fairfield, it will be visible in the evening sky, becoming accessible around 19:00 (EST), 46° above your south-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 21:44, 64° above your southern horizon. It will continue to be observable until around 02:42, when it sinks below 21° above your western horizon.

The geometry of the alignment

This optimal positioning occurs when it makes its closest approach to the point in the sky directly opposite to the Sun – an event termed opposition. Since the Sun reaches its greatest distance below the horizon at midnight, the point opposite to it is highest in the sky at the same time.

At around the same time that 1036 Ganymed passes opposition, it also makes its closest approach to the Earth – termed its perigee – making it appear at its brightest in the night sky. This happens because when 1036 Ganymed lies opposite to the Sun in the night sky, the solar system is lined up so that 1036 Ganymed, the Earth and the Sun lie in a straight line with the Earth in the middle, on the same side of the Sun as 1036 Ganymed.

On this occasion, 1036 Ganymed will pass within 0.408 AU of us, reaching a peak brightness of magnitude 9.2. Nonetheless, even at its brightest, 1036 Ganymed is a faint object beyond the reach of the naked eye; binoculars or a telescope of moderate aperture are needed.
