2017 TV4

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to the Golden Gate Bridge
• Classified as a Near Earth Asteroid (NEA)
• Classified as a Potentially Hazardous Asteroid (PHA)
• See orbit simulation

Overview

2017 TV4 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 TV4 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2017 TV4 orbits the sun every 1,280 days (3.50 years), coming as close as 0.86 AU and reaching as far as 3.76 AU from the sun. Based on its brightness and the way it reflects light, 2017 TV4 is probably between 0.419 to 0.938 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.

No Close Approaches

2017 TV4's orbit is 0.04 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.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2017 TV4's orbit is determined by observations dating back to April 24, 2004. It was last officially observed on April 11, 2018. The IAU Minor Planet Center records 211 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
