Asteroid 10 Hygiea Distance from Earth
The distance of Asteroid 10 Hygiea from Earth is currently 420,497,921 kilometers, equivalent to 2.810855 Astronomical Units. Light takes 23 minutes and 22.6301 seconds to travel from Asteroid 10 Hygiea and arrive to us.
The following chart shows the distance of Asteroid 10 Hygiea from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
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 10 Hygiea from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Asteroid 10 Hygiea to Earth
Between January 2013 and December 2100, the closest approach of Asteroid 10 Hygiea to Earth happens on Fri May 20 2078 at a distance of 1.747301 Astronomical Units, or 261,392,555 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 10 Hygiea brightness
The current visual magnitude of Asteroid 10 Hygiea is 11.10.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 10 Hygiea, 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 10 Hygiea 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 10 Hygiea rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):
The rise and set times are defined as the time at which the upper limb of Asteroid 10 Hygiea 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.
