Spring equinox and planetary hike - reloaded

Dear All,
Maybe you already realized its getting dark later and bright earlier. We can’t break tradition and its time again, as every year: We will observe the spring equinox position of our sun and will walk the planetary hike nearby!
Along this hike the distances of the planets are displayed in the scale of 1:1 billion. So every meter on the hike equals 1 Mio km in space, and we will try to reach Pluto in 5 km distance. Please be aware this could turn out to be a tiring hike, I expect 12 km including the way back (4 hrs) through the Lainzer Tiergarten.
Take some food and drinks with you, on the way back we could rest in the Restaurant Schießstätte, pending mood and physical condition.
The Spring equinox will take place March 20th and marks the beginning of spring on the northern hemisphere. The spring equinox is the day when night and day are equally long and the days become longer again.
