Flyby geometry
Ecliptic flyby of 2018 VR3 at 2036-07-02 00:34 UTC Top-down view of the ecliptic, Earth at the centre, for the 2036-07-02 00:34 UTC close approach of 2018 VR3. Catalogue miss distance 157.0 LD · 6.03 × 10⁷ km. The curve is the geocentric path from 2036-06-29 to 2036-07-05, with a mark at UTC midnights and an arrow for the direction of motion. The circle is the Moon’s mean orbit; the Moon is plotted at closest approach. A ray shows the Sun’s direction. The labelled distance is the full separation. The drawn radius is the part that lies in the ecliptic plane. The path is a geocentric ecliptic ephemeris from JPL Horizons. The inset is a heliocentric view and is approximate.
