1991 VG is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1991 VG as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
1991 VG orbits the sun every 383 days (1.05 years), coming as close as 0.98 AU and reaching as far as 1.09 AU from the sun. Based on its brightness and the way it reflects light, 1991 VG is probably between 0.004 to 0.017 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
1991 VG's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
1991 VG has 9 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Nov. 7, 2038 | 10,500,072 | 2.966 |
| May 28, 2039 | 8,957,553 | 1.473 |
| Feb. 26, 2040 | 25,666,438 | 5.916 |

1991 VG's orbit is determined by observations dating back to Nov. 6, 1991. It was last officially observed on June 1, 2017. The IAU Minor Planet Center records 73 observations used to determine its orbit.
1991 VG can be reached with a journey of 386 days. This trajectory would require a delta-v of 4.425 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 1,307,792 potential trajectories and launch windows to this asteroid.
