'''S/2019 S 1'''是[[土星]]的一颗天然[[卫星]]。其发现于2021年11月16日由爱德华·阿什顿、布雷特·格拉德曼、让-马克·佩蒂和迈克·亚历山德森通过加拿大-法国-夏威夷望远镜在2019年7月1日至2021年6月14日期间的观测结果宣布<ref name="announcement"/>。<br />
<br />
S/2019 S 1的直径约为5公里，以顺行的方式绕土星公转，平均距离为11.2百万公里，公转周期为443.78天，轨道倾角为44°，轨道离心率为0.623。它属于因纽特群顺行不规则卫星，并且是土星最内侧的不规则卫星之一<ref name="DP53"/>。它可能是[[土卫二十四|土卫二十四（基维尤克）]]和[[土卫二十二|土卫二十二（伊耶拉克）]]的碰撞碎片，这两颗卫星具有非常相似的轨道要素<ref name=Denk>[https://tilmanndenk.de/outersaturnianmoons/s2019_s1/ S/2019 S 1] {{Wayback|url=https://tilmanndenk.de/outersaturnianmoons/s2019_s1/ |date=20230106185058 }}: Tilmann Denk</ref>。<br />
<br />
这颗卫星的离心轨道每千年会多次使其靠近[[土卫八]]，最近距离可达1.5百万公里<ref name=Denk/>。<br />
