Mata panas nya siti bintang ba tengah Sistem Solar. Iya nya sfera plasma angat ti besai sereta nyau deka sempurna, dipanas nyentukka nyadi pijar nengah reaksyen fusi nuklear dalam teras iya, mansutka tenaga ari permukaan iya tebal agi nyadi penampak ti tampak enggau radiasyen inframerah enggau 10% ba tenaga ultraviolet. Iya jauh nyadi pun penatai kuasa ti pemadu beguna ngagai pengidup ba Bumi. Mata panas udah nyadi objek ti dipebasaka dalam mayuh budaya. Iya udah nyadi subjek tengah ungkup pansik astronomi kenyau ari jeman kelia.
