Asteroid 87 Sylvia Distance from Earth

The distance of Asteroid 87 Sylvia from Earth is currently 491,455,186 kilometers, equivalent to 3.285175 Astronomical Units. Light takes 27 minutes and 19.3180 seconds to travel from Asteroid 87 Sylvia and arrive to us.

The following chart shows the distance of Asteroid 87 Sylvia 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 87 Sylvia from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest approach of Asteroid 87 Sylvia to Earth

Between January 1900 and January 2100, the closest approach of Asteroid 87 Sylvia to Earth happens on Mon Aug 22 2095 at a distance of 2.153633 Astronomical Units, or 322,178,839 kilometers:

NOTE: values for the closest approach are computed with a sampling interval of 1 day.

Asteroid 87 Sylvia brightness

The current visual magnitude of Asteroid 87 Sylvia is 13.08.

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 87 Sylvia, 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 87 Sylvia rise and set times

Today's Asteroid 87 Sylvia 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 87 Sylvia 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.

Visualization of Asteroid 87 Sylvia Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Asteroid 87 Sylvia with respect of the Sun and the orbits of the major planets. The position of Asteroid 87 Sylvia and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!
