Diane Hine - Sister Planet

An ocean flowed on Venus eons past
Before a body blow reversed her spin
And now alas, unlike her earthly twin
Her waters to the heavens have been cast.
Tectonic plates, unoiled, locking fast
And no sure passage frees the heat within
The skin and core are thermally akin
No dynamo protects from cosmic blast.
And lighter gas is swept away by rays
Ten miles deep, from pole to pole she's wrapped
In densest greenhouse gas, her body steeps.
Each blistered night, a hundred plus earth days
In Vulcan's ashy forge forever trapped
And with sulphuric acid tears she weeps.
