Abstract
Near-Earth asteroid (3200) Phaethon is the primary target for the Demonstration and Experiment of Space Technology for INterplanetary voYage, Phaethon fLyby and dUst Science Phaethon fLyby with reUSable probe (DESTINY+) mission, currently being developed by the Japan Aerospace Exploration Agency (JAXA). The size of Phaethon is measured to be about 5–6 km, although numbers derived by different techniques are not in strict agreement: radar measurement suggests an sphere with a diameter of 6.2 km, or a top-shaped figure with equivalent spherical diameter of 5.5 km (Taylor et al. 2019), while two thermophysical models based on infrared data suggest a spherical diameter of 5.1 ± 0.2 km (Hanuš et al. 2016) and 4.6^(+0.2)_(-0.3) km (Masiero et al. 2019), ≳2σ different from radar data.
