Progress and Perspective of Solar System Science using Subaru

Science Sessions - Solar System

Subaru is a powerful tool for detecting faint structures and small objects in the solar system. In the past 20 years, surveys by ground-based observations such as SDSS and Pan-STARRS as well as those from space such as Akari and NEOWISE were carried out. A number of solar system small bodies have been discovered, and their orbital distribution, surface composition, physical characteristics have been investigated. Subaru also worked on some surveys, and this telescope turned out much more efficient for detecting smaller solar system bodies than any other surveys do.

Subaru has also served as an indispensable tool for space explorations. It has provided various planetary explorations such as New Horizons or Hayabusa with fundamental information so that the missions’ scientific values go enhanced to a great deal. Subaru has also supplied complementary data that spacecraft mission cannot principally bring in, as part of simultaneous observation with the missions.

In this session, we review and discuss how the solar system science was carried out, promoted and stimulated over the twenty years of the Subaru telescope. We will also overview on-going and future projects and related individual studies in this field. The main objective is to share new information in the solar system, which Subaru has substantially extended since the start of its operation.
