Mars doesn't stay in one constellation. It moves through the zodiac constellations over time, just like the Sun and Moon do. To find out what constellation Mars is currently in, you'll need to consult a star chart or an astronomy website that tracks planetary positions.

For example, you can use websites like:

* Stellarium: This website and app lets you view a realistic simulation of the night sky from any location on Earth.

* In-The-Sky.org: This website provides detailed information about astronomical events, including planet positions.

* TheSkyLive.com: This website offers a live view of the night sky and displays the current position of planets.
