SkyKeepsake page about the star Okab.
Okab is a relatively nearby star in the constellation Sge, cataloged as CMa 3.001. It is situated at a distance of 85.31 light years from Earth, positioned roughly 286.3525 degrees north and 13.8631 degrees east. This particular star is known for its consistent, albeit weak, brightness – visually magnitude of 3.001. Its long-term proper motion at 6.575 mas/yr means it’s drifting slowly through the sky, and it moves about -95.91 mas/yr. This makes it a relatively secure identifier in astronomical surveys.
Okab’s recognizability in the sky stems from its spectral type – it exhibits primarily hydrogen lines at its spectral type of G-type. However, this is a fairly basic classification, and the star doesn’t boast a particular colour or large size. It doesn’t display any notable red or infrared emission associated with a specific phase of its stellar evolution. Given its relatively humble distance, it isn't expected to display significant evolution, and possesses minimal radial velocity. This relatively gentle movement minimizes any dramatic influence on its observable characteristics.
Given its observed characteristics, someone might choose Okab as a symbolic dedication reflecting unwavering stability and quiet composure. The star is considered a constant point of observation, providing a steady beacon for astronomers to track the movement of celestial bodies through the cosmos.
