Stellar is a new, in-development mod planning to add all 8 planets of our Solar System (excluding Earth) as dimensions to Minecraft.
WHAT'S IN STELLAR?
+Fake Stone, craftable into Chainmail Armor
+Floating Brown Concrete Powder, a slightly dirt-like block somewhat similar to Brown Concrete Powder, but floating.
+Mercury, a dimension to enter the closest planet to the Sun, alongside a Mercury Transporter to ignite the portal from a Stone frame.
==1.0: THE MERCURY UPDATE==
+Fake Stone can be crafted into Chainmail Armor and looks indistinguishable to Stone.
+Floating Brown Concrete Powder looks like a dirt block but is meant to be (sort of) Brown Concrete Powder. However, unlike sand/gravel/concrete powder, this block does not have gravity.
+The planet Mercury was added, as a dark, desolate wasteland of Fake Stone and Floating Brown Concrete Powder.
