The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 4 Vesta from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest approach of Asteroid 4 Vesta to Earth

Between January 2013 and January 2100, the closest approach of Asteroid 4 Vesta to Earth happens on Sun Jun 7 2076 at a distance of 1.137518 Astronomical Units, or 170,170,256 kilometers:

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 4 Vesta, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.

Asteroid 4 Vesta rise and set times

Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London

Today's Asteroid 4 Vesta rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 76.2°
Max altitude: 52.3°
Azimuth: 283.8°

The rise and set times are defined as the time at which the upper limb of Asteroid 4 Vesta touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
