据新华社报道，哈雷彗星，人类发现并记录的首颗周期彗星，将于本月初抵达远日点之后开始“转身”，预计于2061年7月28日“回归”。哈雷彗星不仅是人类发现并记录的首颗周期彗星，还是目前已知的短周期彗星中唯一一颗能用肉眼直接看到的彗星，每隔约76.1年就会回归一次。这次哈雷彗星抵达远日点，标志其本轮回归周期已经过半。中国天文学会会员、天津市天文学会理事赖迪辉表示，哈雷彗星早在公元前613年被中国古代《春秋》记载：“秋七月，有星孛入于北斗”，这也是目前所知有关哈雷彗星的最早记录。
哈雷彗星由英国天文学家哈雷命名，他也是近代这颗彗星的发现者。他曾预测这颗彗星将在1758年末出现，后来它“如约而至”，可惜哈雷当时已经过世了。距离目前最近的一次哈雷彗星回归是1986年。
虽然哈雷彗星将在太阳辐射作用下分解成彗头和彗尾，状如扫帚，但由于彗星的轨道时常受到大行星引力的影响而发生变化，因此哈雷彗星过近日点的精确时间还存在变数。
哈雷彗星的回归无疑将挑战人类的视觉极限，但这颗人类发现并记录的首颗周期彗星将再次引起全球关注。它的回归时间距上一次回归已过去70多年，下一次回归将在2061年7月28日，让我们拭目以待，共同见证哈雷彗星带来的视觉盛宴！

According to the Xinhua News Agency, Harlequin comet, the first periodic comet discovered and recorded by humans, will begin its “turnaround” journey after arriving at the far side of the orbit on the月初. This celestial body is not only the first periodic comet discovered and recorded by humans but also the only one that can be seen with the naked eye. After every 76.1 years, it returns to the sun. This time, the arrival of Harlequin comet at the far side of the orbit marks the halfway point of its current orbit.

Harlequin comet is named after British astronomer James Bradley, who was also the discoverer of this comet. He predicted its appearance in 1758, but Harlequin did not live to see it. The last time it returned was in 1986.
Although Harlequin comet will be visible in the solar radiation and will be broken down into a彗tail and彗 head, its precise time of arrival at the近日 point still remains uncertain due to the changing orbit of the celestial body.
The return of Harlequin comet will undoubtedly challenge human visual limits, but this celestial body, which is the first periodic comet discovered and recorded by humans, will once again attract global attention. Its next return is expected on July 28, 2061. Let’s look forward to the celestial event!
