Mars, known as the Red Planet, is a mostly dry and dusty place. A variety of colors can be seen on the surface, including the predominant rusty red the planet is known for. This rusty red color is iron oxide, just like the rust that forms here on Earth when iron oxidizes - often in the presence of water.

Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons, and weather. It has a very thin atmosphere made of carbon dioxide, nitrogen, and argon. There are signs of ancient floods on Mars, but now water mostly exists in icy dirt and thin clouds. On some Martian hillsides, there is evidence of liquid salty water in the ground.Click, to see the large size. ▶ BIG FOTO
Mars is one of the easiest planets to spot in the night sky - it looks like a bright red point of light. It has two moons named Phobos and Deimos and one day on Mars takes a little over 24 hours. It makes a complete orbit around the Sun (a year in Martian time) in 687 Earth days, which can be seen in real time on our Planetarium dial.Click, to see the large size. ▶ BIG FOTO
Despite being inhospitable to humans, robotic explorers - like NASA’s new Perseverance rover - are serving as pathfinders to eventually get humans to the surface of this mysterious and intriguing Red Planet.The smallest mechanical Planetarium in the world
This is the ultimate way to carry the universe closely to your heart. Our in-house designed module gives you the smallest mechanical heliocentric planetarium in the world.

It displays real time the solar orbits of Mercury, Venus, Earth, Mars, Jupiter and Saturn. It also shows you the minutes, hours, date and month. The result is a magnificent spectacle that continues to fascinate in all its complex mechanical beauty.Click, to see the large size. ▶ BIG FOTO
This is astronomical watchmaking at the highest level, intricately designed and executed. Our Planetarium is one of the most complicated watches in our collection, a fitting tribute to the grand masters of planetarium design such as Nicolaas Copernicus, Johannes Kepler, Christiaan Huygens and Eise Eisinga.This smallest mechanical Planetarium in the world is located at the 6 o’clock position. (0.)The Sun is positioned exactly in the middle of the Planetarium. The planet closest to the Sun is Mercury. Mercury is followed by Venus, Earth, Mars, Jupiter and Saturn. The planets orbit around the sun as follows:
EISE EISINGA PLANETARIUMDISCOVER THE SOLAR SYSTEM
THE OLDEST WORKING PLANETARIUM IN THE WORLD
Suspended from the ceiling of the living room of a beautiful canal house in Franeker, is the oldest still working planetarium in the world. This accurately moving model of the solar system was built between 1774 and 1781 by the Frisian wool comber, Eise Eisinga.
WHO WAS EISE EISINGA
Eise Eisinga was born in Dronrijp on February 21, 1744. He attended primary school there. Like many children, at that time, he had to work at home, which his case was in his father’s wool combing establishment. In addition to combing wool, he inherited his father’s interest in matters such as astronomy and mathematics. He was so curious that he went to Franeker every week, where he studied Euclides’s maths books with Willem Wijtses, a wool dyer. At the age of 24, Eisinga married Pietje Jacobs, after which he settled in Franeker in 1768, working as a wool comber.
THE END OF TIME
On May 8, 1774, a special constellation of planets formed. In the early morning, Mercury, Venus, Mars, Jupiter and the moon were positioned closely in the sky. It was claimed that the mutual forces of these celestial bodies would knock the earth off its path and cause it to be burned up by the sun. A preacher from Bozum, Eelco Alta, made this prediction. In April 1774, the Leeuwarder Courant published a piece about the writing of this ‘lover of truth’, as he called himself. His piece of writing carried the title: ‘Philosophical concerns about the conjunction of the planets’. Alta’s ideas caused a lot of unrest among the population. The authorities attempted to intervene by banning the piece of writing, but the damage had already been done.
NO NEED TO PANIC
Eisinga’s vast knowledge of mathematics and astronomy came in handy when, in May 1774, turmoil broke out in response to Eelco Alta’s prediction. In order to give the people a correct picture of the solar system, he built a model of the solar system in his living room. Only seven years passed between his very first idea and the final realisation of this project. Since 1781, Eisinga’s model has closely followed the paths of the 6 planets in our solar system. This makes it the oldest still-functioning planetarium in the world.
