Hygiea olarak bilinen asteroit ku\u015fa\u011f\u0131ndaki c\u00fcce gezegen ailesinin yeni bir \u00fcyesi olabilir.<\/p>\n

Ayr\u0131ca teleskop g\u00f6r\u00fcnt\u00fcleri, Hygiea’n\u0131n neredeyse k\u00fcresel bir yap\u0131ya sahip oldu\u011funu ortaya koyuyor.

Ara\u015ft\u0131rmac\u0131lar, 28 Ekim\u2019de Nature Astronomy\u2019de bir rapor yay\u0131mlad\u0131. Buna g\u00f6re Hygiea, 430 kilometre boyuyla ve 950 kilometrelik \u00e7ap\u0131yla, g\u00fcne\u015f sistemimizde ke\u015ffedilen en k\u00fc\u00e7\u00fck c\u00fcce gezegen olan Ceres\u2019i yenecek.<\/p>\n
