Interstellar Asteroid A/2017 U1

Pole, Pericenter, and Nodes of the Interstellar Minor Body A/2017 U1  by C. de la Fuente Marcos, R. de la Fuente Marcos

  Here, we explore some peculiar orbital features of the recently discovered asteroid A/2017 U1, which is a clear outlier when considering the average value of the eccentricity of known hyperbolic comets. As for the orientation of its orbit in space, the orbital plane of A/2017 U1 seems to be away from any obvious clusters present for this population. The orbital nodes of A/2017 U1 are well away from the paths of the planets of the Solar System and the Sun. All these orbital properties appear to confirm A/2017 U1 as the first known interstellar asteroid.

Origin of Interstellar Object A/2017 U1 in a Nearby Young Stellar Association?  by Eric Gaidos, Jonathan P. Williams, Adam Kraus

   We suggest that the kinematics and properties of interstellar object A/2017 U1 point towards its formation in a protoplanetary disk in the ~45 Myr-old Carina or Columba young stellar associations, and subsequent ejection with a low peculiar velocity (1-2 km/sec) during or soon after planet formation inside the ice line. This scenario predicts that the Solar System will encounter more such objects with radiants similar to that of A/2017 U1. 

Implications for planetary system formation from interstellar object 1I/2017 U1 (`Oumuamua)  by David E. Trilling, Tyler Robinson, Alissa Roegge, Colin Orion Chandler, Nathan Smith, Mark Loeffler, Chad Trujillo, Samuel Navarro-Meza, Lori M. Glaspie

  The recently discovered minor body 1I/2017 U1 (`Oumuamua) is the first known object in our Solar System that is not bound by the Sun's gravity. Its hyperbolic orbit (eccentricity greater than unity) strongly suggests that it originated outside our Solar System; its red color is consistent with substantial space weathering experienced over a long interstellar journey. We carry out an simple calculation of the probability of detecting such an object. We find that the observed detection rate of 1I-like objects can be satisfied if the average mass of ejected material from nearby stars during the process of planetary formation is ~20 Earth masses, similar to the expected value for our Solar System. The current detection rate of such interstellar interlopers is estimated to be 0.2/year, and the expected number of detections over the past few years is almost exactly one. When the Large Synoptic Survey Telescope begins its wide, fast, deep all-sky survey the detection rate will increase to 1/year. Those expected detections will provide further constraints on nearby planetary system formation through a better estimate of the number and properties of interstellar objects.

 The tumbling rotational state of 1I/‘Oumuamua

by Wesley C. Fraser, Petr Pravec, Alan Fitzsimmons, Pedro Lacerda, Michele T. Bannister, Colin Snodgrass & Igor Smolić 

The discovery of 1I/2017 U1 (1I/‘Oumuamua) has provided the first glimpse of a planetesimal born in another planetary system.
Oumuamua was probably set tumbling within its parent planetary system and will remain tumbling well after it has left ours.
