美国国家航空航天局 (NASA)-每年,土星的卫星泰坦 (Titan) 都会偏离其行星。它漂移了多远?关于4英寸 (11厘米
案例简介:每年,土星的卫星土卫六都在离它的星球稍远的地方漂移。它漂移了多远?每年约4英寸 (11厘米)。当月球绕轨道运行时,其引力会拉动行星,从而在经过时导致行星暂时隆起。随着时间的流逝,产生的能量从行星转移到月球,将其推得越来越远。这项发现是使用我们的 @ NASASolarSystem卡西尼号前往土星的任务中的数据进行的,2017年结束了。虽然科学家知道土星在太阳系的早期形成于46亿年前,但当行星的环及其80多个卫星系统形成时,还有更多的不确定性。修正后的漂移速率表明,月球开始时更接近土星,这意味着整个系统的扩张速度比以前认为的更快。单击bio中的链接以获取更多信息。信用: 美国宇航局/JPL-加州理工学院/空间科学研究所 # SolarSystem # 土星 # 泰坦 # 天文学 # 美国宇航局 # 卡西尼

案例简介:Each year, Saturn's moon Titan drifts a little farther away from its planet. How far does it drift? About 4 inches (11 cm) per year. As a moon orbits, its gravity pulls on the planet, causing a temporary bulge in the planet as it passes. Over time, the energy created transfers from the planet to the moon, nudging it farther and farther out.The discovery was made using data from our @NASASolarSystem Cassini mission to Saturn, which ended in 2017. While scientists know that Saturn formed 4.6 billion years ago in the early days of the solar system, there's more uncertainty about when the planet's rings and its system of more than 80 moons formed. The revised rate of its drift suggests that the moon started out much closer to Saturn, which would mean the whole system expanded more quickly than previously believed.
