The parent of the Quadrantid meteor shower is the inactive solar system small body (196256) 2003 EH₁. EH₁ has likely only gone dormant in the past few hundred years, and may be related to the bright comet C/1490 Y1. Compared with the other best-studied inactive meteor shower parent (3200) Phaethon, EH₁ has received comparatively minimal characterization of its surface properties. We present the first reflectance spectrum and additional photometry of EH₁, as well as new spectra of the nuclei of three nearly dormant comets P/2006 HR₃₀ (Siding Spring), 364P/Pan-STARRS, and 249P/LINEAR for comparison. We also present new short-term high-resolution orbital integrations of these bodies for context. EH₁s spectrum is red in color below 0.8 μm in between C and D types, consistent with previous photometric measurements, but is blue beyond 0.8 μm until at least 1.02 μm. 249P and 364P have both red slopes consistent with C taxonomic types and HR₃₀ has a classic comet nucleus D-type slope. If the downturn in EH₁’s spectrum is due to an absorption feature, magnetite and olivine are plausible candidates, but more data are needed. 249P and 364P have similar recent and historical dynamical evolutions in addition to their similar surface properties. We discuss the interrelation between the dynamical histories and modern surfaces of these four objects and suggest avenues for further study to better constrain how the Quadrantids and Geminids were created.

象限流星雨的父级是不活动的太阳系小物体（196256）2003 EH ₁。EH ₁可能仅在过去几百年中就处于休眠状态，并且可能与C / 1490 Y1彗星有关。与其他研究最好的非活动流星雨母体（3200）Phaethon相比，EH ₁的表面特性表征相对较少。为了比较，我们展示了EH ₁的第一反射光谱和附加的光度学，以及三个几乎处于休眠状态的彗星P / 2006 HR ₃₀（侧面弹簧），364P / Pan-STARRS和249P / LINEAR的原子核的新光谱。我们还介绍了这些机构的新的短期高分辨率高分辨率轨道积分，以供参考。H₁小号光谱红色低于0.8颜色μ米在C和d的类型，与先前的光度测量一致之间，但是蓝色超出0.8 μ米直到至少1.02 μ微米。249P和364P都具有与C分类法类型一致的红色斜率，而HR ₃₀具有经典的彗核D型斜率。如果EH ₁下滑的光谱归因于吸收特征，磁铁矿和橄榄石是可能的候选物，但还需要更多数据。249P和364P除具有相似的表面特性外，还具有相似的近期和历史动力学变化。我们讨论了这四个物体的动力学历史和现代表面之间的相互关系，并提出了进一步研究的途径，以更好地限制象限和双子座的产生。
