The primary star belongs to the spectral class A0p and has a visual magnitude of 4.33, and the companion belongs to the spectral class A3m and has an apparent magnitude of 5.23. The stars orbit each other with a period of over 700 years. The primary star has 2.3 solar masses and is 3...
A comet's origins in the primitive nebula can be probed by examining the degree to which fossil deuterium is enriched compared to the protosolar abundance. Calculations of the temporal and radial evolution of the deuterium enrichment in the solar nebula can reproduce existing D/H measures for co...

A ballistics analysis of the Deep Impact ejecta plume: Determining Comet Tempel 1's gravity, mass, and density In July of 2005, the Deep Impact mission collided a 366 kg impactor with the nucleus of Comet 9P/Tempel 1, at a closing speed of 10.2 km s−1. In this... James,E.,Ri...
The Oort Cloud is important because it offers an explanation for the paths of long-period comets. Long-period comets have non-disc like orbits that last for decades to thousands of years. Without the concept of the Oort Cloud, the understanding of comet orbits is limited. ...
Messier 2 was discovered by the Italian-born astronomer Jean-Dominique Maraldi (Giovanni Domenico Maraldi) on September 11, 1746, while he and French astronomer Jacques Cassini were observing a comet. The French astronomer and comet hunter Charles Messier added the cluster to his catalogue on ...
The invention is related to a system of identification of the location of a matrix-like sample tray on a plane (2) in an equipment for the treatment of the samples. The sample tray is placed in a frame having an L-shaped electrically conductive piece (8). The equipment for the treatment...
