The Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses. [3] The total mass of the Omega Nebula is an estimated 800 solar masses. [4]
A cost estimator will typically use estimating software to estimate their bid price for a project, which will ultimately become part of a resulting construction contract. Some architects, engineers, construction managers, and others may also use cost estimating software to prepare cost estimates for purposes other than bidding such as budgeting ...
Omega Sagittarii, which is Latinized from ω Sagittarii, is a binary star system in the constellation of Sagittarius, [9] near the eastern constellation border with Capricornus. It is formally named Terebellum / t ɛr ɪ ˈ b ɛ l əm /. [10] [11] This system has a yellow hue and is faintly visible to the naked eye with an apparent visual ...
Omega Octantis, (latinized from ω Octantis), is a solitary, [14] bluish-white hued star located in the southern circumpolar constellation Octans. It has an apparent magnitude of 5.87, [2] allowing it to be faintly seen with the naked eye. Based on the object's parallax measurements, it is estimated to be 328 light years distant. [1]
Omega Piscium (Omega Psc, ω Piscium, ω Psc) is a star approximately 106 light years away from Earth, in the constellation Pisces. It has a spectral type of F4IV, meaning it is a subgiant/dwarf star, and it has a temperature of 6,600 kelvins. It may or may not be a close binary star system. Variations in its spectrum were once interpreted as ...

The distance estimate comes from computing how far the object must be to make its observed absolute velocity appear with the observed angular motion. Expansion parallaxes in particular can give fundamental distance estimates for objects that are very far, because supernova ejecta have large expansion velocities and large sizes (compared to stars).
Omega 1 Aquilae, which is Latinized from ω 1 Aquilae, is the Bayer designation for a single [8] star in the equatorial constellation of Aquila. With an apparent visual magnitude of 5.2 [ 2 ] it is a faint, yellow-white hued star that can be seen with the naked eye in dark skies.
