明天要关闭网上买彩票的神秘物体是什么?

 

“ T 他反对在2020年12月1日仅通过31,605英里之外的网上买彩票, 
可能不是小行星;它’s probably the Centaur upper stage rocket booster that helped lift 美国宇航局’1966年,命运多Survey的Surveyor 2飞船驶向月球。”

美国宇航局's ill-fated Surveyor 2 spacecraft headed for the moon in 1966 for survey work, but ”
美国宇航局’s ill-fated Surveyor 2 spacecraft launched for the moon on September 20, 1966, on an an Atlas/Centaur from launch site 36A at Cape Kennedy, Florida. Liftoff took place at 12:31:59.824 UT. 美国宇航局: “Surveyor separation from the Centaur took place at 12:44:32.4 UT. During the 9.8 s midcourse maneuver firing at 5:00 UT on 21 September, one of the three vernier engines failed to ignite, resulting in an unbalanced thrust that caused the spacecraft to tumble at roughly 1.22 rev/s. The nitrogen gas system operated to stabilize the spacecraft, but could only marginally reduce the spin rate. Multiple attempts to fire the no. 3 engines to salvage the mission were unsuccessful. At terminal descent the vernier engines and retrorockets were fired at about 9:34 UT on 23 September. Signals ceased abruptly at 9:35:00, indicating it impacted the Moon, at a point estimated to be roughly 5.5 N, 12 W. The Surveyor program involved building and launching 7 Surveyor spacecraft to the Moon at a total cost of $469 million.”

N2020年10月30日,新墨西哥州阿尔伯克基– Earth has captured gravitationally a tiny object between 15 and 33 feet in diameter that was first thought to be an asteroid. The object, dubbed 2020 SO by astronomers, will come “extremely close” within 31,605 miles of our planet at 3:50 a.m. ET on December 1, according to 美国宇航局’位于加利福尼亚州帕萨迪纳的喷气推进实验室的近地天体研究中心(CNEOS)。 2020年9月17日在夏威夷毛伊岛进行的Pan-STARRS调查首次发现了这一点。

但是当美国国家航空航天局(Nasa)近地物体研究中心(CNEOS)主任Paul Chodas’位于加利福尼亚州帕萨迪纳的喷气推进实验室首次看到了神秘物体’在轨道上,他“倒转时钟”并运行了物体’s向后旋转以确定过去的位置。

美国宇航局 reports that Chodas found that the object had already passed relatively close to Earth several times over the past decades, including one moment that indicated it could have actually launched from Earth.

“ 1966年SO的可能路径之一是在1966年9月下旬将天体非常靠近网上买彩票和月球。这就像尤里卡时刻,对月球任务的发射日期的快速检查显示与Surveyor 2任务相匹配。”

2020年SO被网上买彩票捕获’它的引力是2020年11月8日的,而计算表明它会作为一颗临时卫星保留在我们行星的轨道上,直到2021年3月才逃回太阳周围的新轨道。
