Asteroid 1999 KW4 brightness

The current visual magnitude of Asteroid 1999 KW4 is 16.96.

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 1999 KW4, 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 1999 KW4 rise and set times

Today's Asteroid 1999 KW4 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 1999 KW4 touches the horizon, consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.

Visualization of Asteroid 1999 KW4 Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Asteroid 1999 KW4 with respect of the Sun and the orbits of the major planets. The position of Asteroid 1999 KW4 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!
