3C 147(B0538+498)是一个致密陡谱源的(CSS)类星体[3],发现于1964年。它位于御夫座之中,在天空中与五等五车增十七相距不远。

遥远星系的“距离”取决于使用哪种距离测量方法。它的红移值为0.545,[1][2] 来自这个活动星系核的光估计要花费大约51亿年才能到达地球。[2] 但是因为宇宙的膨胀,现在这个星系的进动距离大约是64亿光年(1974 Mpc)。[2]

超长基线阵列(VLBA)观测表明存在一个由两个组成天体A和B所控制的复杂的中心区域。[3] 该射线源的两个组成天体的分离视向速度似乎正以超光速运动(并非实际速度),速度为1.2 ± 0.4 c,而且在不断加速。[3]
