The tree of life is universal to all humanities and remains the same.
Venus still relates to Tiphereth, even on the physical planet Venus, which is still a form of earth, the base materialization of matter in the physical plane.
Mars still relates to Geburah, the sphere of justice, even on the physical planet Mars, who have their Malkuth as the body of Samael, the Martian Logos.
We are fittingly on the bottom of the tree of life because our planet is fallen. The other planets of the solar system are not fallen, and do relate to higher levels of being, manifesting superior forces from the Sephiroth above.
However, for the sake of organization and clarity, Malkuth just means a terrestrial kingdom with four divisions of beings: minerals, plants, animals and humanoids, whether this is on Mars, Venus, Mercury, etc.
The planetary influences are the same throughout the cosmos, albeit perhaps in different languages and names, since the tree of life exists everywhere and is universal.
Planets are particular, but the influences flowing through them are spiritual and universal, everywhere. This is the meaning of the seven mighty rays, characteristics, or influences of the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn.
While these are planets we know of, these also consist of spiritual rays or influences that organize all of creation.
The stars are Chrisified planets with resurrected humanities. This is why the Qur'an states:
By the sky containing great stars (houses of the Solar Angels),
by the Promised Day,
by the Witness and the Witnessed:
perish the Men (hasnamussen) of the Ditch (the abyss who failed to conquer their lunar mind)!
The fire, abounding in fuel (in the tritocosmos or center of any planet, the infernal worlds),
above which they sat (in Malkuth before falling)
as they were themselves
witnesses to what they did to the faithful.
They were vindictive towards them only
because they had faith in Allah,
the All-mighty, the All-laudable,
to whom belongs the kingdom of the heavens (Deuterocosmos, Macrocosmos, Ayoscosmos, and Protocosmos)
and the earth (Mesoscosmos and Microcosmos),
and Allah is witness to all things.
-Qur'an 85:1-8
