How can that be believed? seeing (now in the Creation) it was not the terrour and astonishment but the perfection, integrity, beauty, and felicity of the pure and spotlesse Universe, which God intended. 13–15, Bibcode: God sayd, Let there be Lights in the firmament of the heaven, to divide the day from the night, and let them be for signes, and for seasons, and for dayes, and years.Īnd let them be for lights in the firmament of the heaven, to give light upon the earth.

Consequently, the Chinese name for η Andromedae itself is 奎宿一 ( Kuí Sù yī, English: the First Star of Legs.) Visual companion Įta Andromedae has a visual companion star of apparent visual magnitude 11.5, BD+22☁53B, visible 129.2 arcseconds away. ![]() In Chinese, 奎宿 ( Kuí Sù), meaning Legs (asterism), refers to an asterism consisting of η Andromedae, 65 Piscium, ζ Andromedae, ε Andromedae, δ Andromedae, π Andromedae, ν Andromedae, μ Andromedae, β Andromedae, σ Piscium, τ Piscium, 91 Piscium, υ Piscium, φ Piscium, χ Piscium and ψ¹ Piscium. This allowed a more complete orbit to be computed and, in 1993, published. In observations made from 1990 to 1992, Eta Andromedae was resolved interferometrically by the Mark III Stellar Interferometer at Mount Wilson Observatory, California, United States. Because spectroscopy only reveals the radial velocity of a star towards or away from the viewer, such a computation does not determine all orbital elements. Its orbit was computed in 1946 from spectroscopic observations. Η Andromedae system as seen from earth orbit, M 33 in backgroundĮta Andromedae was discovered to be a double-lined spectroscopic binary in a series of spectra taken in 18. ![]()
