THE CONSTELLATIONS DON'T MOVE. THE EARTH DOES AND THAT IS WHY WE HUMANS THINK IT'S MOVING WHEN THEY ARE NOT.
They are not. There are constellations in every direction.
It does not move, it is the Earth that moves.
That is the most common direction in which tornadoes travel, but they can move in any direction.
Yes, the constellation Eridanus appears to move across the night sky due to Earth's rotation. It generally moves from east to west as the night progresses. This motion can vary slightly depending on the time of year and your location on Earth.
Just like every other celestial object, the stars and their apparent patterns move from east to west in the sky as time goes on.
Most tornadoes in the northern hemisphere move to the northeast.
Constellations appear to move in the sky due to the Earth's rotation on its axis. As the Earth rotates, different constellations become visible at different times of the night. This motion is also why constellations appear to shift positions throughout the year.
Stars and constellations appear to move in the night sky due to the Earth's rotation on its axis. As Earth spins, different stars and constellations become visible while others disappear below the horizon. This motion gives the illusion of stars and constellations moving across the sky.
They don't - why do you think they do?
Constellations are a result of accidental collinearity. Most stars in a constellation are separated by huge distances but their position is such that they appear to lie close to one another and appear to move together in a single shape. In addition, most constellations are based on pretty impressive imagination of ancient civilisations which managed to see images of their mythical characters or animals in these shapes.
A tornado can move in any direction, but the most common direction of travel is southwest to northeast. Southeast-moving tornadoes are not uncommon.
Many of the currently-used constellations were invented in ancient Greece; others were added a few centuries ago, mainly by Europeans. In 1922, the IAU defined the current constellations, including the official limits between the constellations.
