'''GJ 3379'''（Giclas 99-49）是在[[獵戶座]]內最靠近[[太陽]]恆星，距離只有17.5[[光年]]。這顆[[主序帶|主序]]星是一顆[[紅矮星]]，[[光譜類型]]為M3.5V。它的[[視星等]]為11.33，[[絕對星等]]為12.68，所以裸眼是看不見這顆恆星的。它位於獵戶座的左上部，在[[參宿四]]的下方；它的[[徑向速度]]是 +30.0公里/秒，依據[[SIMBAD]]的資料，這顆恆星被歸類為[[耀星|焰星]]。<br />
<br />
在過去，這顆恆星曾經與[[太陽系]]有過近距離的接觸。大約在{{nowrap|163,000 ± 3,000 years}}以前，它曾接近至{{nowrap|4.30 ± 0.10 ly}} {{nowrap|(1.32 ± 0.03 pc)}}<ref name=al36_11_816/>。<br />
