Asteroid 9 Metis

Asteroid 9 Metis is a main-belt asteroid that orbits the Sun between Mars and Jupiter. It was discovered on April 25, 1848, by Irish astronomer Andrew Graham. The asteroid is named after the Greek goddess of wisdom and cunning, Metis. Metis has a relatively small diameter of about 90 kilometers and a rotation period of about 5.5 hours. Its orbit is somewhat eccentric, with a semi-major axis of approximately 2.39 astronomical units (AU) and an orbital period of about 3.69 years. Metis is also a member of the Flora family of asteroids, a group of objects that share similar orbital and physical properties and are believed to have formed from a common parent body.

Asteroid 9 Metis is currently in the constellation of Gemini.

The current Right Ascension of Asteroid 9 Metis is 06h 20m 13s and the Declination is +26° 08’ 37” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current magnitude of Asteroid 9 Metis is 8.85 (JPL).

Asteroid 9 Metis Distance from Earth

The distance of Asteroid 9 Metis from Earth is currently 171,779,845 kilometers, equivalent to 1.148277 Astronomical Units. Light takes 9 minutes and 32.9959 seconds to travel from Asteroid 9 Metis and arrive to us.

The following chart shows the distance of Asteroid 9 Metis 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 9 Metis from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Asteroid 9 Metis to Earth

Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 9 Metis to Earth happens on Thu Dec 7 1916 at a distance of 1.107641 Astronomical Units, or 165,700,805 kilometers:

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

Asteroid 9 Metis Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 9 Metis, 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.

Visualization of Asteroid 9 Metis Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Asteroid 9 Metis with respect of the Sun and the orbits of the major planets. The position of Asteroid 9 Metis 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!
