Flyby geometry
Ecliptic flyby of 2022 JJ2 at 2044-05-14 09:44 UTC Top-down view of the ecliptic, Earth at the centre, for the 2044-05-14 09:44 UTC close approach of 2022 JJ2. Catalogue miss distance 116.5 LD · 4.48 × 10⁷ km. The curve is the geocentric path from 2044-05-11 to 2044-05-17, 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. At closest approach the object is north of the ecliptic. The path is a geocentric ecliptic ephemeris from JPL Horizons. The inset is a heliocentric view and is approximate. Sun 116.5 LD · 4.48 × 10⁷ km 2044-05-14 09:44 UTC Earth Moon Heliocentric, approximate
