The synchronous binary system measures approximately 800 m mi off us in diameter. It was discovered by astronomers of the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, on 14 September 1998. It has one minor-planet moon, discovered in September 2003. It has an orbital period of 14.53 hours and measures approximately 48% of its primary, or 380 meters. It is one of seven known Aten binaries as of 2017. Interaction with Earth 1998 RO 1's orbit is very eccentric, with an aphelion beyond the orbit of Mars and a perihelion inside the orbit of Mercury. It has an orbital period of 360.29 days (0.99 years) and makes close approaches to Earth. But 1998 RO 1 makes closer approaches to other inner planets, especially Mars. Its closest approach to a planet between 1950–2200 was to Mars, as it passed 0.00898 AU km on from Mars on 18 March 1964, and will pass 0.0054 AU km on from Mars on 12 October 2065.

The satellite was discovered from lightcurve observations going from 13 to 28 September 2013, and was confirmed by radar observations from the Arecibo Observatory one year later. It is in a very close orbit to 1998 RO 1, with a semi-major axis of 800 m ft on and an eccentricity of 0.06, giving it a periapsis of 752 m ft on and an apoapsis of 848 m ft on. The satellite takes 14.54 hours to complete one orbit around 1998 RO 1. Numbering and naming This minor planet was numbered by the Minor Planet Center on 10 September 2003. As of 2018, it has not been named. References 2010-09-10 last obs.
