Where is Mars tonight?

Mars is the fourth planet from the Sun, a cold desert world about half as wide as Earth. Iron oxide dust gives it its red colour, and about every 26 months it comes close to Earth and shines brightest around opposition.

Earth: with a mass of 70 kg you would weigh what 70.0 kg weighs on Earth, a force of 686 newtons.

Gravity values are NASA’s, measured at the equator and including the effect of the world’s rotation. The motion is shown without air: on Earth a real ball would be slowed down a little, and in the much denser air of Venus a lot.

How to use this page

Choose your place and a night at the top: tonight by default, or one of the dates under it. The tiles show when Mars rises, is highest and sets, and the numbers that matter for that night. Below them you find where it is right now, the sky in 3D with Mars marked, finder charts, the year ahead and the facts.

What the numbers mean

Rises and sets
When the top edge of the disc meets a flat horizon, with the bending of light by the air included, as in almanacs. A time on another day carries its date.
Highest
When it crosses the meridian, due south or due north, and its height above the horizon then.
Direction and height
The compass point and azimuth to face, counted from north through east, and the angle above the horizon. A fist at arm’s length covers about 10°.
Distance and apparent size
How far away it is from Earth’s centre at that moment and how wide it looks in the sky, in arcminutes (′) or arcseconds (″).
Magnitude
Brightness: the smaller the number, the brighter. About 6 is the faintest the eye sees under a dark sky.

How accurate it is

Positions and times come from Astronomy Engine. In our tests positions agree with NASA JPL’s Horizons to within one arcminute, and rise and set times of the Sun and the Moon to within two minutes. Times assume a flat horizon at your place, so hills and buildings change when you actually see it rise or set. Methodology

Frequently asked questions

Why do the times change from night to night?

Earth turns once a day, and the body moves along its own path at the same time, so it rises and sets at a slightly different time each day. The Moon moves fastest and rises about 50 minutes later each day.

Why does a time show another date?

The page follows the night that starts on the evening of the chosen date. A rise, highest point or set after midnight belongs to the next date, so it carries that date.

Do the times include hills and buildings?

No. They are for a flat horizon. Hills, trees and buildings make a body rise later and set earlier than the page shows.

How do I find it in the sky?

Use the direction and height at its best time, then the finder charts further down to place it among the stars. The 3D sky shows it from your place at any time of the night.
