1 lunar distance = 384,400 km. Nominal distance; uncertainties vary by object and orbit solution. Source: JPL close-approach data in the catalogue snapshot. Estimated from absolute magnitude H = 25.77, assuming a visual albedo between 0.05 and 0.25. This is not a measured diameter.

Flyby geometry
Ecliptic flyby of 2026 TV8 at 2026-10-21 23:47 UTC Top-down view of the ecliptic, Earth at the centre, for the 2026-10-21 23:47 UTC close approach of 2026 TV8. Catalogue miss distance 4.75 LD · 1.83 × 10⁶ km. The curve is the geocentric path from 2026-10-18 to 2026-10-24. The circle is the Moon’s mean orbit and 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 south of the ecliptic. The path is a geocentric ecliptic ephemeris from JPL Horizons. The Moon’s position is approximate. Sun 19 Oct 4.75 LD · 1.83 × 10⁶ km 2026-10-21 23:47 UTC Earth Moon
