Asteroid macroporosity indicates extensive internal fracturing and void spaces within rubble-pile asteroids
Is it true that asteroid macroporosity indicates extensive internal fracturing and void spaces within rubble-pile asteroids?
Yes. Evidence from asteroid studies confirms that rubble-pile asteroids feature significant macroporosity arising from internal void spaces and gaps between constituent boulders.
Verdict: SUPPORTED · 4 sources for, 0 against · Last checked
The retrieved literature consistently supports the premise that rubble-pile asteroids contain extensive macroporosity and void spaces between their component boulders and blocks, although recent analyses suggest that the exact contribution of macroporosity versus microporosity can sometimes be modulated by efficient boulder packing.
