Effects of a rogue planet passing between the Earth and the Moon? The plot of Thundarr the Barbarian got me thinking about the science behind 


  the passage of a runaway planet between the Earth and the Moon


and its effect on the Earth and Moon themselves, as well as their orbits.

For the following scenario:


planet has half the mass of Earth, and is moving at 16km/s
moving perpendicular to the plane of the ecliptic
passes directly between the Earth and the Moon with closest distance to Earth of 192,500 km


What sort of effects, if any, might this have on Earth and those of us residing there during the passage in later months and years?
It doesn't look good. 

Tidal effects. The passing planet will certainly cause disruptive tides as it passes. The exact height of the tides would be hard to calculate as it depends on how the tides flow around the land masses, but the effects would be much greater than lunar tides. The tidal effect could also have consequences for the earthquakes.

Disruption to the orbit of the moon. The moon's orbit will be significantly altered. It could cause the moon to enter an elliptical orbit (with consequences for tides).  There would not be enough disruption to cause the moon to leave Earth orbit immediately

Disruption to Earth's orbit.  The orbit of Earth would also be significantly changed, it could enter a significantly elliptical orbit, this would change the amount insolation over the year and greatly change the Earth's climate

If the disruption were significant enough, it could bring the Earth's orbit uncomfortably close to that of Venus, this could result in further disruption to the moon's orbit

Fortunately space is big, and even if there are a lot of rogue planets out there, it would be a very rare event for one to pass so close to star
