NGC 4293 是一个位于后发座北部的透镜状星系，由英国天文学家威廉·赫歇尔于1787年3月14日发现。他将这个星系形容为“大而长，可分辨，长度为6-7角分”。这个星系位于五诸侯增六的西北偏北方向，是室女座星系团的一员。^[5] 其和室女座星系团与地球的距离可能大致相同，约为5400万光年。^[4]该星系的尺寸约为5.3×3.1角分。^[5]

该星系的型态类型为(R)SB(s)0/a，类型编号中的SB0/a表明该星系含有可勉强分辨的蜿蜒旋臂且其核球为棒状。而“(s)”标记则表明这个星系在其核球周围没有环状结构。^[6]^[8] 该星系的恒星形成区域仅限于星系中心附近。^[9]此外，该星系的星盘外侧存在扰动，表明其与其他天体发生了引力相互作用^[10]。

该星系属于一种名为低电离星系核的常见活跃星系，意味着该星系的视觉光谱主要由处于低能电离态的气体发射线组成。这可能是由于一个位于星系核球的超大质量黑洞正以较低的速率累积物质，该黑洞的质量约为7007590000000000000♠5.9×10⁷ M_⊙。^[11]由于该星系距地球较近，人类探测到了该星系由于热能活动而产生的无线电波。^[12]
