Workshop Location and Dates

We are happy to announce the Apophis T–9 Years: Knowledge Opportunities for the Science of Planetary Defense workshop scheduled for April 23–24, 2020 at the Hôtel Le Saint Paul, Nice, France.

The Apophis workshop is being held on dates adjacent to a Community Workshop on ESA’s Hera Mission, held in Nice April 20–22, 2020. Joint participation is welcome, but you must register for each meeting separately. Details on the Hera Meeting may be found at

Purpose and Scope

This workshop will explore the dynamical details and corresponding science opportunities presented by the April 13, 2029 near-miss passage of the asteroid Apophis. Knowledge is the first line of planetary defense, and the 2029 Apophis encounter is a once-per-thousand-year opportunity for investigating an asteroid as large as 350 meters passing within 6 Earth-radii. Time is of the essence as we have less than a decade to plan Earth-based and possible in-situ missions whose measurements can deliver unprecedented detailed knowledge on the physical nature of Apophis as the prototype example (poster child) of potentially hazardous asteroids.

The workshop will consist of invited talks and contributed presentations, including contributed posters.
