Asteroid 99942 Apophis brightness

The current visual magnitude of Asteroid 99942 Apophis is -100.00.

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 99942 Apophis, 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 99942 Apophis rise and set times

Today's Asteroid 99942 Apophis 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 99942 Apophis 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 99942 Apophis Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Asteroid 99942 Apophis with respect of the Sun and the orbits of the major planets. The position of Asteroid 99942 Apophis 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!
