لأول مرة.. رصد قمر حول “قزم بني” خارج المجموعة الشمسية

ما يعرفه ريفو عن الخبر

رصد العلماء لأول مرة قمر محتمل يدور حول قزم بني خارج المجموعة الشمسية.
يبلغ وزن القمر المحتمل نحو 90% من كتلة كوكب المشتري ويتم دورته في 170 يوما.
استخدم العلماء مطياف أشعة وطريقة السرعات الشعاعية لرصد الجسم نظرا لعدم إمكانية رؤيته مباشرة.
يعد هذا الاكتشاف أول دليل على وجود أقمار تدور حول أقزام بنية خارج حدود نظامنا الشمسي.

ذكرت مجلة “Nature” أن علماء الفلك تمكنوا، ولأول مرة، من رصد قمر يدور حول “قزم بني” خارج حدود المجموعة الشمسية.
