Observaciones 18-marzo-2017


Confirmation of four NEOCP objects, one still in the possible comet confirmation page with an arc of 36 days, the preliminary orbit's semi axis  a=419 AU and eccentricity e=0.9957 show this could be in a nearly parabolic path coming from the outer Solar system.

Also, a potentially hazardous Apollo type asteroid  2017 FE1

MPEC F44: 2017 FE1 [a=2.43,e=0.62,i=3.1,H=20.2,PHA]

Epoch 2017 Feb. 16.0 TT = JDT 2457800.5                 MPC
M 329.28424              (2000.0)            P               Q
n   0.26080549     Peri.  201.74297     -0.14480126     +0.98836469

e   0.6227606      Incl.    3.08318     -0.41178547     -0.10298275

The perihelion distance q can be calculated from the semi axis a and eccentricity e as,

q = a * (1-e) = 0.9152546 AU

The Earths semi axis being 1 AU, this means this object crosses the Earth's orbit.

And two new Amor type NEOs,
