Core of Halley's Comet
This photo of Halley's comet was taken by the Russian Vega 2 spacecraft, one of two Soviet probes (Vega 1 was the other) to rendezvous with the comet during its 1986 trip through the solar system in March 1986. The closest approach of Vega 1 to Halley was 8890 km while Vega 2 had a close encounter at 8030 km.

Composite Image of Halley's Comet
This image is composed of 68 images of varying resolution. The data at the brightest point on the nucleus is at the highest resolution (50 m).
The Sun comes from 30 deg above the horizontal to the left and is 17 deg behind the image plane (observation phase angle of 107 deg). The night side of the nucleus can be seen silhouetted against a background of bright dust in the far-field. Jets can be seen originating from two regions on the nucleus. Structure can be seen within the jets.
A bright area is seen within the night side of the nucleus. We believe this to be a hill or mountain approximately 500 m high.
