Gudja is a red giant roughly 3x the mass of the Sun that has already left the main-sequence and blew up to a size of 71 solar radii. At its position only 18° north of the celestial equator with an apparent magnitude of 4.09, it is visible almost everywhere on Earth. It's rushing towards us at a speed 1000x of cars on highways. |

Paikauhale is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Hawaii'ian. It is the name of HIP 81266 (τ Sco, HR 6165) in constellation Sco.
Etymology and History
Au-haele, Hōkū-‘ula, and Paikauhale are documented as three stars in a line, running from north to south. Two of the most reliable sources – Mary Puku‘i and Rubellite Johnson – both identify Hōkū-‘ula as Antares (α Sco), which makes Au-haele Alniyat (σ Sco) and Paikauhale τ Sco.
"Paikauhale" (pă'i-kă'u-hā'-le) literally translates to "to go gadding about from house to house" in the Hawaiian language, according to the Pukuʻi & Elbert Hawaiian Dictionary[1].

The name was adopted by the IAU WGSN on 2018/08/10.
Currently, Paikauhale is a young blue-white (B-type) star at its main-sequence phase of stellar evolution. As it has a mass of 15 solar masses, it will end its life in a majestic explosion called "supernova". So, in a far future (i.e. in ~6.5 million years from now), it will become a red supergiant and look like neighbouring Antares looks now. Yet, by that time, Antares itself will have gone supernova already.
