About These Units
Nanosteradian (nsr)
A nanosteradian (nsr) equals 10⁻⁹ steradians or about 42.5 square arcseconds. Used in precision optical measurements, astronomical source size calculations, and high-resolution imaging system specifications. Individual pixels in space telescopes may subtend nanosteradians.
Square Arcsecond (arcsec²)
A square arcsecond equals (1/3600)² of a square degree or about 2.35×10⁻¹¹ steradians. One square arcminute = 3,600 square arcseconds. Measures individual star disks, exoplanet host star separation, and high-resolution imaging pixels.
