The movement of the solar system
libre 12
The Earth and other planets move around the Sun, but it does not stand still in space. Therefore, the movement of the solar system occurs in the boundless expanse of the Universe. 
The speed of the Sun
Without stopping anywhere for a single moment, the Sun is carried along its galactic orbit at a speed of 270 kilometers per second and for every second is approaching 20 kilometers to the constellation of Lyra.
Rushing in this direction, the Sun takes with it the whole world of planets - all the large planets, asteroids and comets. So, we, the inhabitants of the Earth, participate in this eternal run of our daytime luminary. Consequently, our Earth, since its existence, is getting closer to the constellation of Lyra every day.
Earth in the space of the universe
The Earth occupies every day a certain position relative to the Sun, - approximately the same as it occupied relative to it on this day last year. But this does not mean that the Earth has returned to its previous point in the space of the universe.
Throughout its long life, the Earth has never been at any point in the universe twice. Each point of space it leaves forever, irrevocably, never to return to it again. And all of this is due to the motion of the Sun!
The Earth's spiral motion
The Earth participates in the Sun's run and, therefore, cannot describe any closed curve. It moves with colossal speed through space in some spiral.
The motion of a railroad express train will seem to us absolutely insignificant in comparison with the speed of the Earth's movement in space, similar, for example, to the motion of a turtle in comparison with the speed of a railroad express train.
The speed of the Earth orbiting the Sun is 90 times the speed of sound. We are at work, sitting, with each heartbeat we move in space for dozens of kilometers, participating as passengers in all the movements of our planet.
So, we stay on the Earth as on a fast-running spaceship, which forever and at an incredible speed, together with the Sun and all the bodies of the solar system, is traveling in the abyss of the Universe.
