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 Gemini, at a distance of 265,128,070 kilometers from Earth.

The distance of Asteroid 433 Eros from Earth is currently 265,128,070 kilometers, equivalent to 1.772272 Astronomical Units. Light takes 14 minutes and 44.3720 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.
