Why are visual binaries and eclipsing binaries relatively rare compared to spectroscopic binaries?
Visual Binaries are rare compared to spectroscopic binaries because visual binaries have widely separated members bright enough to be observed and monitored separately.The orbital plane of the pair of stars in Eclipsing Binariesare almost edge-on to our line of sight. In this case we observe a periodic decrease of starlight intensity as one member of the binary passes in front of the other.Spectroscopic Binaries are too distant from us to be resolved into separate stars, but they can be indirectly perceived by monitoring the back-and-forth Doppler shifts of their spectral lines as the stars orbit one another and their line-of-sight velocities vary periodically.To summarize, Visual Binaries and Eclipsing Binariesare harder to identify and observe compared to the Spectroscopic Binaries, therefore Visual Binaries and Eclipsing Binaries are much more rare.McMillan, Chaisson , et. al.

If you weighed 65 kg. on Earth how much would you weigh on Mars?
If your weight on earth (with a gravitational acceleration of approx. 9.8 m/s^2) is 45 kg, then your mass would be 45 / 9.8 = 4.6 - Meaning that on Mars (which has a gravitational acceleration of 3.7 m/s^2), your weight would be 4.6 * 3.7 = 17 kg. To summarize and simplify, the conversion factor from Earth to Mars weight is approx 3.7/9.8=0,38.
What does NGC in astronomy mean?
The 'New General Catalogue' was an update to Sir John Herschel's 'General Catalogue,' hence the name 'NGC'. Henry Dreyer and Annie Jump Cannon compiled the NGC in the late 19th and early 20th century. This catalog, like its predecessor the GC, focused on cataloging the non-stellar deep sky objects found in astro-photographic plates. The nature of many of these objects was not understood until many years later.John Herschel's General Catalog (GC) of nonstellar objects of 1864 contained over 5,000 objects, while J.L.E. Dreyer's New General Catalogue (NGC), together with its two supplements (Index Catalog I and II, IC) summarize over 13,000 deep sky objects. Each catalogue entry is of the form NGC, and the types of objects catalogued include galaxies, nebulae, open and closed clusters and globular clusters. On-line versions of the catalogue are available at a number of sites, including http://www.seds.org/~spider/ngc/ngc.html

The difference between disk and halo stars?
Which of the following statements correctly summarize key differences between the disk and the halo?Answer:Clusters of young stars are found only in the disk.Stars in the disk all orbit in the same direction and nearly the same plane, while halo stars have more randomly oriented orbits.Gas and dust are abundant in the disk but not in the halo.Disk stars come in a broad range of masses and colors, while halo stars are mostly of low mass and red.
