Like the fact Uranus is upside down.
, its interior has been cooling down and the whole planet has been contracting slightly in volume. This has led to the formation of wrinkles, or scarps, on its surface as the inside shrinks.published in Nature Geoscience
Grabens are small strips of ground that drop down between two parallel faults in the surface, less than a kilometre wide and usually less than 100m deep. Given their short lifespan, and the number still visible on Mercury’s surface, the team was able to determine significant shrinkage has been happening in the past 300 million years.Until then, here are some more weird facts about our cosmological neighbourhood.Uranus is tilted almost a=t a right-angle to its orbit Spinning on a tilted axis by 98 degrees, it is basically lying on its side. This is thought to have been caused by a collision with a large object early in the solar system’s history.
It takes eight minutes for light from the Sun to reach Earth. But it takes around 200,000 years for light to escape from the centre of the Sun to its surface.
