  • رصد علماء الفلك لأول مرة قزماً أبيضاً بلون أخضر مصفار باهت في مجرة درب التبانة.
  • نتج هذا اللون النادر عن تغيرات كيميائية وتراكم مواد كوكبية مثل الكالسيوم والليثيوم والصوديوم على سطحه.
  • يقع هذا النجم على بعد حوالي 280 سنة ضوئية من الأرض.
  • أدت تصادمات ذرات الصوديوم مع الهيليوم إلى تغيير مستويات الطاقة الذرية ومنحه توهجه الأخضر.
