  author={Klaus Wilhelm and Bhola N. Dwivedi},
The findings of Micheli et al. (Nature2018, 559, 223–226) that 1I/2017 U1 (`Oumuamua) showed anomalous orbital accelerations have motivated us to apply an impact model of gravity in search for an explanation. A small deviation from the 1/r potential, where r is the heliocentric distance, is expected for the gravitational interaction of extended bodies as a consequence of this model. This modification of the potential results from an offset of the effective gravitational centre from the…

The close-approach of the Sun by asteroid 2000 B19 provides further evidence for MOdified Newtonian Dynamics (MOND) and Asymmetric Near-Field (ASNF) gravity by observational data, which shows added


On the Anomalous Acceleration of 1I/2017 U1 ‘Oumuamua
We show that the P ~ 8 hr photometric period and the astrometrically measured A_(ng) ~ 2.5 × 10^(−4) cm s^(−2) non-gravitational acceleration (at r ~ 1.4 au) of the interstellar object 1I/2017
Non-gravitational acceleration in the trajectory of 1I/2017 U1 (‘Oumuamua)
‘Oumuamua—the first known interstellar object to have entered the Solar System—is probably a comet, albeit with unusual dust and chemical properties owing to its origin in a distant solar system.
Tidal fragmentation as the origin of 1I/2017 U1 (‘Oumuamua)
The first discovered interstellar object (ISO), ‘Oumuamua (1I/2017 U1) shows a dry and rocky surface, an unusually elongated shape, with short-to-long axis ratio c ∕ a  ≲ 1∕6, a low velocity relative

Micheli et al. (Nature 559:223, 2018) reported that a seven-parameter fit to the orbit of 1I/2017 U1 ‘Oumuamua indicated a non-gravitational acceleration in the anti-Solar direction, and attributed
1I/2017 U1 (`Oumuamua) is Hot: Imaging, Spectroscopy and Search of Meteor Activity
1I/2017 U1 (`Oumuamua), a recently discovered asteroid in a hyperbolic orbit, is likely the first macroscopic object of extrasolar origin identified in the solar system. Here, we present imaging and
Could Solar Radiation Pressure Explain ‘Oumuamua’s Peculiar Acceleration?
'Oumuamua (1I/2017 U1) is the first object of interstellar origin observed in the solar system. Recently, Micheli et al. reported that 'Oumuamua showed deviations from a Keplerian orbit at a high
New Insights into Interstellar Object 1I/2017 U1 (‘Oumuamua) from SOHO/STEREO Nondetections
Object 1I/2017 U1 (`Oumuamua) is the first interstellar small body ever discovered in the solar system. By the time of discovery, it had already passed perihelion. To investigate the behavior of

Observations of the first interstellar minor object 1I/2017 'Oumuamua did not reveal direct signs of outgassing that would have been natural if it had volatile-rich composition. However, a recent
Why is interstellar object 1I/2017 U1 (`Oumuamua) rocky, tumbling and possibly very prolate?
The recently discovered first interstellar object 1I/2017 U1 (`Oumuamua) has brightness that varies by a factor of 10, a range greater than that of any Solar System asteroid, a spectrum
Tumbling motion of 1I/‘Oumuamua and its implications for the body’s distant past
Models of the Solar System’s evolution show that almost all the primitive material leftover from the formation of the planets was ejected to the interstellar space as a result of dynamical
