Asteroid Omwamwi exceeds the possible speed

Астероид Оумуамуа превышает возможную скорость

Asteroid Omwamwi

The observed trajectory cannot be fully explained by the gravity of the Sun, planets, moon, Pluto.

Asteroid Omoloi, the first ever interstellar object discovered in the Solar system, experiences an additional acceleration, which cannot be explained either by the gravity of the Sun and planets or the influence of the solar wind. It is reported N+1.

A team of astronomers coordinating center for the study of objects in near Earth ESA led astrometric observations Omwamwi to Refine its trajectory. Scientists used data from the Hubble telescopes, VLT in Chile, and CFHT in Hawaii. Received over 400 measurements of the trajectory.

The analysis showed that the observed trajectory cannot be fully explained by the gravity of the Sun, planets, moon, Pluto and 16 of the largest bodies in the main asteroid belt, as well as relativistic effects.

Scientists have discovered a very weak “external” acceleration, which has varied inversely with the radius of the orbit.

The authors of the study concluded that the most likely cause is a reaction force of the jets of gas and dust that become volatile substance on the surface of an object approaching the Sun. The effect of “degassing” known with regard to comets, but still signs of cometary activity in Omwamwi was found.

Scientists have suggested that the dust on the surface of the object is too coarse. A cloud of such large particles may not be bright enough to detect, but its presence could explain the speed change Omwamwi.
