In the Arezzo region, where this house is, prices are lower, ranging from 1 million to 4 million euros ($1.14 million to $4.56 million) depending on views and the condition of the property.
Isaac Newton, and others since his day, have shown that the Earth's precession is caused by the gravity of the Moon and Sun acting on the oblateness of the Earth. Since it can be calculated so accurately I have to believe it is true. The obliquity, or angle between the plane of the Earth's orbit and the axis, is about 23 degrees but varies between 22.1 and 24.5 degrees, in-phase with the precession circuit.
Over very long time periods (thousands of years) the direction of Earth's axis slowly changes due to precession. The Earth rotates around once in 24 hours - that's a rate of 1000 miles per hour!. The time it takes for the Earth to rotate completely around once is what we call a day. It's Earth's rotation that gives us night and day. The combined effect of the Earth's tilt and its orbital motion result in the seasons.
