Mars Sky Charts and Coordinates
This is a simplified sky chart, showing where Mars is now with respect to the brightest stars and constellations.
More advanced sky charts are available on TheSkyLive for this object: 1) the Online Planetarium which is interactive and allows to select dates and additional objects to visualize; and 2) the Live Position and Data Tracker which provides the highest precision position data and features deep sky imagery from the Digitized Sky Survey.
Mars Rise and Set Times
Today's Mars rise, transit and set times from Greenwich, United Kingdom [change]. All times are relative to the local timezone Europe/London.
The following table lists the ephemerides of Mars computed for the past and next 7 days, with a 24 hours interval. Click on each row of the table to locate Mars in our Online Planetarium at the chosen date.

Distance of Mars from Earth
The following chart shows the distance of Mars from Earth as a function of time. Distance data is measured in Astronomical Units and sampled with a 2 days interval.
The reported distances might be inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of Mars is also available as a real time updated value in the Live Position and Data Tracker.
Light Curve of Mars
The following chart is the predicted light curve (visual magnitude as a function of time) of Mars, 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.
