6047 (1991 TB1) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1991 TB1 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 TB1 orbits the sun every 641 days (1.75 years), coming as close as 0.94 AU and reaching as far as 1.97 AU from the sun. Based on its brightness and the way it reflects light, 1991 TB1 is probably between 0.719 to 1.607 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
1991 TB1's orbit is 0.14 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
1991 TB1 has 4 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|March 15, 2099||26,236,525||13.072|
|March 17, 2106||21,643,852||13.846|
|March 18, 2113||20,966,421||14.793|
|March 19, 2120||24,931,618||15.989|
1991 TB1's orbit is determined by observations dating back to March 20, 1985. It was last officially observed on Jan. 14, 2022. The IAU Minor Planet Center records 802 observations used to determine its orbit.
