Have you understood the solar system correctly?

Illustrations of the solar system do not accurately represent the sizes and movements of planets in the universe.

You may have seen many of these, however, for illustrative purposes these images are often not to scale. Most exaggerate the size of the planets and place them much closer together than they actually are for the viewer to view. If we were to observe the solar system in real life, all of the celestial bodies would be too small, faint, and far apart to be seen with the naked eye.

In the real universe, the solar system resembles the night sky as seen from Earth. In fact, when we look at the night sky, we see a large part of the solar system.

The solar system looks like the night sky seen from Earth.

The planets and their orbits are in real proportions, some of which include Earth’s orbit located much closer to the Sun than the outer planets. (Photo: Space Center).

If simulated at real scale, taking the view from the outside, the easiest object to observe is the Sun, but it is also only a small point of light. Some large planets look like stars, while others are too faint to see.

The real motion of the Earth and the solar system

The planets all revolve around their axis and revolve around the Sun. A person on Earth can feel that they are there, but on a cosmic level that is not the case. The Earth rotates around its axis at a speed of nearly 1700 km/h or 0.5 km/s.

The number may seem large at first glance, but compared to other motions in the solar system and the milky way which affect and create the speed of movement of the entire planet in the universe, it is not an odd number.

Like Earth, the Earth orbits the Sun much faster than itself. The speed of the Earth around the Sun is 30 km/s. After 365 days, the Earth will return to the starting point, or more precisely, close to the starting point, because the Sun is not upright either.

An accurate model of how the planets orbit the Sun

Stars, planets, gas clouds, dust particles, black holes, dark matter, etc. are all in motion. From the observational position of the Earth, about 25,000 light-years from the galactic center, the Sun orbits the Milky Way in an ellipse and completes one revolution in 220-250 million years.

Estimates of the speed of the Sun during this journey are around 200 to 220 km/s, a large number compared to both the speed of rotation of the Earth and the orbital speed of the planet around the Sun. , both of which are inclined at an angle to Earth’s orbit. with the plane of motion of the Sun around the galaxy.

However, throughout the journey, the planets remain in the same plane, with no overshooting or dragging phenomenon as some illustrations often show.

368 km/s is the speed at which humans travel through space.

And the entire galaxy is not stationary, but is moving due to the gravitational pull of matter in the universe. In the local cluster, a complex of over 50 galaxies, including the Milky Way, can measure the speed of the Milky Way’s motion relative to the largest galaxy in the cluster, .

This galaxy is heading towards our Sun at a speed of 301km/s. Taking into account the movement of the Sun in the Milky Way, Andromeda and the Milky Way are moving towards each other at about 109 km/s.

Entire galaxies and local clusters move due to unseen forces.

At the largest scale, not only the Earth and the Sun are moving, but entire galaxies and local clusters are moving due to unseen forces. (Photo: ASA/ESA).

Local clusters, although large and composed of many galaxies, are not isolated. Other galaxies and surrounding clusters all exert gravity. Scientists estimate that these structures far from the Earth generate an additional speed of 300 km/s.

Add all these movements together, the Earth revolves around itself, the Earth revolves around the Sun, the Sun moves around the galaxy, the Milky Way towards Andromeda and the local cluster is attracted and repelled by the surrounding regions , is how fast we actually move through the universe.

The speed of the movement reaches up to 368 km/s in a particular direction, plus or minus about 30 km/s, depending on the time of year and the direction in which the Earth is rotating, according to Ethan Siegal, PhD, PhD in astrophysics at the University of California, studying in Florida, author of the blog Starts With Ą Bang.

Our planet and the planets revolve around the Sun in one plane, and the entire plane moves in an elliptical orbit through the galaxy.

Since every Sun-like star in the galaxy also moves in an ellipse, the solar system appears to move in and out of the galactic plane every tens of millions of years, and takes about 200 to 250 million years to complete. in a circle around the galaxy. .
