Asteroid 433 Eros

Asteroid 433 Eros is an S-type asteroid located in the inner part of the asteroid belt. It was discovered on August 13, 1898 by Gustav Witt in Berlin and named after the Greek god of love. Eros is approximately 34.4 × 11.2 × 11.2 km in size, making it one of the larger near-Earth asteroids. Its orbital period is 1.76 years, and its average distance from the Sun is about 1.46 astronomical units (AU). Eros is notable for being the first asteroid to be orbited and landed on by a spacecraft, NASA's NEAR Shoemaker, in 2000.

Asteroid 433 Eros is currently in the constellation of Aquarius.

The current Right Ascension of Asteroid 433 Eros is 22h 01m 27s and the Declination is -15° 17’ 12” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current magnitude of Asteroid 433 Eros is 13.01 (JPL).

Asteroid 433 Eros Distance from Earth

The distance of Asteroid 433 Eros from Earth is currently 187,283,727 kilometers, equivalent to 1.251914 Astronomical Units. Light takes 10 minutes and 24.7113 seconds to travel from Asteroid 433 Eros and arrive to us.

The following chart shows the distance of Asteroid 433 Eros 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 433 Eros from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Asteroid 433 Eros to Earth

Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 433 Eros to Earth happens on Mon Jan 24 2056 at a distance of 0.149800 Astronomical Units, or 22,409,694 kilometers:

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

Asteroid 433 Eros Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 433 Eros, 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 433 Eros Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Asteroid 433 Eros with respect of the Sun and the orbits of the major planets. The position of Asteroid 433 Eros 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!
