Number of Interstellar Objects by VRO in 2YR


As of November 2021, two interstellar objects (1I/`Oumuamua and 2I/Borisov) have been discovered while traversing the Solar System. While the galactic population of such objects is relatively unconstrained, the forthcoming Vera Rubin Observatory will have a larger field-of-view in which to identify interstellar objects. This question is part of a fortified essay on the origin and composition of interstellar objects like `Oumuamua.

How many interstellar objects will be identified by the Vera Rubin Observatory in its first two years of observations?

This question will resolve to the whole number value of interstellar objects that were first identified by the Vera Rubin Observatory within two years of its first light image. The number of objects discovered by this observatory will be determined by the number of objects with the "I" designation as interstellar with a discovery asterisk corresponding to the Vera Rubin Observatory, as recorded by the Minor Planet Center.

This question will close on the date considered to be "first light" (i.e. first scientific operations) for the Vera Rubin Observatory in Chile. This first light date will be determined as announced by the Rubin Observatory on their website. Resolution will be 2 years and 3 months after first light, to allow 3 months to classify any ambiguous observations.

In the case that Vera Rubin Observatory does not make begin first light or make observations before 2030-01-01, this question will resolve ambiguously.

As of November 17, 2021, the Vera Rubin Observatory is expected to see its first light in January 2023 and scientific operations are set to begin in late 2023.
