Notes. The table lists the time of observation, Apophis’s distance from the Sun r, from Earth Δ, the solar phase angle α, the geocentric ecliptic coordinates λ and β, and the number of photometric data points N. Observations were taken in the R filter and are absolutely calibrated.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
