Expansion 1: Solar System

This expansion brings the observation of planets in the solar system. Only the planets visible to the naked eye are part of this expansion. This extension will be available in a limited edition after the basic game has been released.

A curriculum for schools (edu variant) will also be available. The game treats the five most visible planets of the solar system alongside the Earth.

Game variations: solo / competitive / co-op / edu

Number of players: 1-6

Age: 10+

Playtime: 30-60 min

Available: via Kickstarter Planetary Pledge or Ultimate Astronaut Pledge

What does Solar System add to the game?

This expansion is an extension of the Astronomy part of the game and adds observation cards of the planets, or the so called “wandering stars”, because they can’t be fixed on the star map. The game board works like an orrery of the planets that are visible with the naked eye and with a small telescope. We’ve left out Uranus and Neptune.

Because these planets are so feint and far away, they were only discovered in the 17th and 18th century: Uranus in 1690 and Neptune in 1795. We do mention them in the Edu-booklet, but for educational and observational reasons, we do want to stress, they are unable to be detected by the general public.

The gameplay concentrates on the concept of visibility of planets from the Earth in relation to the Sun. We even Included Venus and Mercury transits among the observation cards.

During the Ecliptic Step of the month, after the first player shifts the Sun on the ecliptic of the Star Map and after laying out new observation cards, the rocky planets shift one position counterclockwise around the Sun. The Gas planets only shift their position after one Earth year.

The basic collections for planets are Rocky and Gas planets.

Visibility is checked with the crossing line through the Sun making a 90° angle with the month marking line of Earth.

When one of the month marking lines are touched by the Earth and Venus or Mercury (if they are aligned on the same side of the Sun), we have a possible transit.

Here some illustrations to show in an elegant and simplified way what the concept of visibility and transit is.

Some can recognize the positions of 2018, apart from the possible transits, but those transits are just there for conceptual reasons. These rare phenomena are explaned in the EDU and INFO booklet.

Don’t miss out on the real Mercury Transit on November 11–12 in 2019!
