\u00c7al\u0131\u015fmaya ili\u015fkin veriler Science dergisinde yay\u0131nland\u0131. Connolly, biliminsanlar\u0131n\u0131n g\u00f6zlemledi\u011fi \u015feyin daha \u00f6nce kuyruklu y\u0131ld\u0131zlarda g\u00f6r\u00fclen bir durum olabilece\u011fini s\u00f6yledi ve ekledi: “Ancak g\u00f6rd\u00fc\u011f\u00fcm\u00fcz \u015fey bu tan\u0131ma uymuyor. Kuyruklu y\u0131ld\u0131zlar\u0131n aktivitesine benzer bir aktiviteye, gaz ve kat\u0131 yap\u0131daki partik\u00fcller e\u015flik etmelidir. Ancak gaz yap\u0131da partik\u00fcl varsa onu g\u00f6remeyiz, burada g\u00f6zlenen sadece y\u00fczeyden \u00e7\u0131kan par\u00e7ac\u0131klard\u0131r.<\/p>\n

Connolly, bu asteroidin sadece 500 metrelik bir \u00e7apa sahip oldu\u011funu ve yeterince d\u00fc\u015f\u00fck bir y\u00fczey yer\u00e7ekimine sahip oldu\u011funu s\u00f6yledi. Bu \u00f6zellikler nedeniyle asteroidin y\u00fczeyinden kaya kopu\u015funun daha kolay olabilece\u011fini ifade eden Connolly, bu kayalar\u0131n hi\u00e7birinin geri d\u00f6nd\u00fc\u011f\u00fcn\u00fc g\u00f6rmedi\u011fini s\u00f6yl\u00fcyor.<\/p>\n
