Gamma Arietis, traditionally named **Mesarthim**, is a stunning binary star system located in the northern constellation of Aries, famous for its striking white-colored stellar components.

The Right Ascension coordinate for Gamma Arietis is approximately **01h 53m 31.8s**, placing it precisely within the celestial coordinates of the Ram constellation.

The Declination coordinate for Mesarthim is roughly **+19° 17' 45"**, positioning it comfortably in the northern celestial hemisphere for observers worldwide.

Mesarthim sits squarely inside the official IAU boundaries of **Aries**, bordered by Triangulum to the north, Pisces to the south and west, and Taurus to the east.

The system is located at an approximate distance of **164 light-years** (about 50 parsecs) away from our solar system, making its light easily viewable through small telescopes.

Discovered by Robert Hooke in 1664, it was one of the earliest double stars ever found. Its components feature glowing white spectral types that are cleanly separated in amateur optics.

The combined apparent magnitude of the system is roughly **3.88**, allowing it to be clearly spotted with the naked eye under moderately dark suburban night skies.

Gamma Arietis reaches its highest point in the night sky during autumn and early winter evenings, particularly around the month of November.

Right Ascension acts like longitude projected onto the sky (measured in hours, minutes, seconds), while Declination acts like latitude (measured in degrees north or south of the celestial equator).
