QSO J0313−1806^[2]是最遥远的，因此也是已知最古老的类星体，发现时的“z”=7.64^[1]。2021年1月，它被确定为已知红移最大（“z”最高）的类星体，已知最古老的超大质量黑洞（SMBH），质量高达7009160000000000000♠(1.6±0.4)×10⁹太阳质量^[3]^[4]^[5]。2021年的公告档案将其描述为在“z”> 7时“规模最大的超大质量黑洞”^[6]。这个类星体击败了之前创纪录的类星体，ULAS J1342+0928^[7]。2023年，UHZ1被发现，创下了最遥远类星体的新纪录，超过了QSO J0313−1806的记录^[8]。

2021年论文作者之一王飞鸽表示，在宇宙存在的这么早就存在超大质量黑洞，这给当前的形成理论带来了问题，因为“最早由大质量恒星产生的黑洞不可能在短短数亿年内长得这么大”^[4]。红移z＝7.642对应于大约6亿年的年龄。
