Rosett Earth Flyby 1
Rosetta Earth Swing-By 1
Introduction
On 04 Mar 2005, the European comet mission Rosetta performed a swing-by at our planet
Earth. It came as close as 1900 km to the surface, at 22h10m UT. It
approached from away from the sun and had its closest approach shortly
after 22h UT, on the illuminated side of the Earth. Rosetta approached
us from an area in the border between the constellations Leo and Sextans,
visible almost all night from the northern and most of the southern hemisphere.
The first observation report was from 28 Feb 2005, it was estimated to be
around 17 mag - see this
image by Thomas Hugentobler from Switzerland. The record for the observation
at the highest distance is held by David Briggs from England, see the 'images'
page.
On the evening of the closest approach, it moved away from the constellation
Sextans after sunset and move towards the direction of the sun, crossing
the complete sky. Europe is favorably placed to follow this event. It
moved faster and faster towards the west, disappearing on the horizon around
22 h UT (23 h CET). Rosetta reach about visual magnitude 8 to 9.
This page gives details about this event with finder charts and finder
tables for the advanced amateur or public observatories.
