摘要
C/1830 F1彗星(Great March Comet)是众多抛物线轨道彗星之一。考虑到对这颗彗星有足够的观测(赤经428次,赤纬424次),计算出一个更好的轨道是可能的。计算基于12阶预测校正方法。这颗彗星的轨道是高度椭圆的,e=0.99792,从计算的平均误差来看,在统计上与抛物线不同。这颗彗星将在数千年内不会返回,因此不会对近地天体构成直接威胁。
A NEW ORBIT FOR COMET C/1830 F1 (GREAT MARCH COMET)
Comet C/1830 F1 (Great March comet) is one of a large number of comets with parabolic orbits. Given that there are sufficient observations of the comet, (428 in right ascension and 424 in declination), it proves possible to calculate a better orbit. The calculations are based on a 12th order predictor-corrector method. The comet’s orbit is highly elliptical, e=0.99792 and, from calculated mean errors, statistically different from a parabola. The comet will not return for thousands of years and thus represents no immediate NEO threat.
