The τ Scorpii (τ Sco) star, was known as Al-Niyat in medieval Islamic period, is a B0V single star with mass of 15 solar mass (M ⊙ ). It means that τ Sco is a massive star that has properties like B-type star such as has 31,440 K temperature effective and so on. The evolution simulation using MESA simulation software was conducted from pre-main sequence phase to red supergiant phase for τ Sco. We obtain that the age of τ Sco currently is 5.22 million years and it’s in main sequence phase. The τ Sco will reach the red supergiant phase at the age of 11.6 million years after formation.
