我们宣布发现了一颗主带彗星（MBC），2010 LH15（也称为2010 TJ 175）。MBC是一种罕见的主带小行星，显示出类似彗星的活动，如尾巴或彗星，由升华引起。因此，MBC帮助我们绘制太阳系挥发物的位置，为我们了解生命的先决条件物质的起源提供了洞察力。然而，MBC已经被证明是难以捉摸的，在110万颗已知的主带小行星中发现的不到20颗。这一发现来自Active Asteroids，这是我们设计的NASA合作伙伴公民科学计划，旨在识别更多这些重要物体。在志愿者将2010年LH15的图像归类为显示活动之后，我们进行了一项后续调查，揭示了跨越近十年的两个时代的活动证据。这一发现是及时的，2010年LH15将于2024年3月通过近日点，最早可能在2023年底开始活动。
We announce the discovery of a main-belt comet (MBC), 2010 LH15 (alternately designated 2010 TJ175). MBCs are a rare type of main-belt asteroid that display comet-like activity, such as tails or comae, caused by sublimation. Consequently, MBCs help us map the location of solar system volatiles, providing insight into the origins of material prerequisite for life as we know it. However, MBCs have proven elusive, with fewer than 20 found among the 1.1 million known main-belt asteroids. This finding derives from Active Asteroids, a NASA Partner Citizen Science program we designed to identify more of these important objects. After volunteers classified an image of 2010 LH15 as showing activity, we carried out a follow-up investigation which revealed evidence of activity from two epochs spanning nearly a decade. This discovery is timely, with 2010 LH15 inbound toward its 2024 March perihelion passage, with potential activity onset as early as late 2023.
