There is also a beautiful planet trail in Rees just across the Dutch-German border in Germany (1:1,000,000,000). The sun is on the Rhine dike / city wall on the east side of the city, and the path continues east on the dike. So up to Jupiter the “sun” (a 1.4 m bronze ball) is just visible on the dike! Pluto is then about 6 km further away.
