Tools for working with the @ESAGaia data and related data sets - jobovy/gaia_tools Sharing a common envelope, the stars are so close they will one day merge to form a single star. Two star systems with known exoplanets, HD 93083 and WASP-66, lie within Antlia, as do NGC 2997, a spiral galaxy, and the Antlia Dwarf Galaxy. Its rotation period is 11.2 days at the equator. Epsilon Eridani is smaller and less massive than the Sun, and has a comparatively lower level of elements heavier than helium. It is a main-sequence star of spectral class K2, which means that… Curtis noticed that these novae were, on average, 10 magnitudes fainter than those that occurred elsewhere in the sky. As a result, he was able to come up with a distance estimate of 500,000 ly (3.2 ×1010 AU). Abstract. In this paper, we present the results of a 12-yr campaign devoted to monitoring the sky brightness affected by different levels of light pollution. D This level corresponds to an approximate total sky brightness of between 20.6 and 20.0 mag/arcsec2 (0.6 to 1.1 mcd/m2). With this sky brightness, the summer Milky Way in Cygnus may be only faintly detectable as a small increase in the sky…
