What Happens If The Sun Moves Away From Earth

The departure of the Sun from the Earth would have catastrophic consequences. The climate would become extremely cold, ecosystems would collapse, and life as we know it would disappear.

What is going to happen on April 23, 2023?

A video is circulating on social networks that states that on April 23, 2023 there will be a solar storm with extremely high radiation, giving a 23% chance to each human being of surviving. However, this is false. Neither NASA nor any other aerospace agency has issued a warning in this regard. Scientists explain that predicting a solar storm with such accuracy is totally impossible. While it is true that solar storms can cause communications problems and affect satellites, they do not represent an imminent danger to life on Earth.

When does the Sun move away from the Earth?

Our planet, Earth, approaches the Sun in its orbit on January 4, 2023, in an event known as Perihelion. At this point, we will be more than 147 million kilometers from the Sun, compared to Aphelion, the farthest point in Earth’s orbit, when we will be more than 152 million kilometers away. This will occur on July 6, 2022.

In short, at the beginning of January we will be approximately 5 million kilometers closer to the Sun than at the beginning of July. Although we may not notice it much, on January 4, 2023 the Earth will be closer to our star.

How many years will it take for the Sun to go out?

If our Sun is 4.5 billion years old, how much longer will it shine? Stars similar to our Sun have a lifespan of approximately 9 or 10 billion years. Therefore, our Sun is approximately halfway through its life. However, there is no cause for concern, as it still has around 5 billion years of life left.

When those 5 billion years pass, the Sun will become a red giant. This means it will get bigger and colder. At that time, it will no longer be the bright yellow sun we know today, but will appear darker and red in color.

In one cartoon, the red giant Sun is shown saying, “It’s pretty cold here.”

More fun in the sun!

What happens if there is no sun?

The Sun is the central star of our solar system and influences all the planets, as well as maintaining their temperature. If the Sun were to disappear, it would have serious consequences for our planet and life as we know it. The light on Earth would come only from the stars of other solar systems, the planets would stop rotating around the Sun due to gravity, temperatures would drop drastically and nature would die as it could not carry out photosynthesis. The oceans would become vast expanses of ice. In short, life on Earth and its environment would disappear and humanity would be seriously affected. To survive, it would be necessary to build a bunker in the center of the Earth to conserve the heat of the core. Despite its drawbacks, the Sun is essential for the existence of all living beings.

Where won’t the sun rise?

The phenomenon of the last sunset of the year occurred in Utqiaġvik, Alaska, a town located in the northern third of Alaska, above the Arctic Circle. This event is not unique to Utqiaġvik, as other areas of northern Alaska also experience this phenomenon due to their location close to the Arctic polar region. The inhabitants of Utqiaġvik, numbering around 4,500 people, witnessed this event last Friday, November 18.

What will happen if the Sun smiles?

NASA has managed to capture a curious image of the Sun in which it appears to have an infinite smile. Through the Solar Dynamics Observatory, the space agency has used an ultraviolet filter to reveal the face of the Sun, which are actually coronal holes in the solar corona. These regions are where the magnetic field is ejected directly into space rather than returning to the surface in a loop. Although the Sun lacks a recognizable face, this image allows us to see it in a peculiar way thanks to the phenomenon of pareidolia. On social networks, users have found various similarities to the Sun, such as the Marshmallow Man from the movie Ghostbusters or certain cookies with eyes and a chocolate smile. However, this is just a coincidence and the Sun is not expected to have a face in the future. The Sun is approximately 4.6 billion years old and is estimated to have around 5 billion years of life left.

What happens if the Moon is closer to Earth?

In the real world, the Moon is not only moving away from the Earth, but it is doing so at a constant rate of 38 centimeters per year since the Earth-Moon system formed. This is because the Solar System is approximately 4.5 billion years old and is already considered mature, meaning there are no planets in chaotic orbits or factors that could cause system-wide chaos.

This stability will continue until the Sun reaches the end of its life in about 5 billion years. However, for this to change, something extreme would have to happen. For example, the presence of a black hole that ventured far enough into the Solar System could significantly modify orbits. Although it is rare for this to happen.

Evidence of the stability of our system is found in the fact that it has remained stable for billions of years. This, among other curiosities of the Solar System, leaves us the option of letting our imagination fly.

Suppose that somehow one day the Moon stops moving away and begins to approach the Earth in leaps and bounds. This would allow us to talk about interesting concepts that are used in astronomy.

As the Moon gets closer, the tides on Earth become more and more extreme. Sea levels would rise and fall more markedly, affecting many people.

What is it called when the Sun is furthest from the Earth?

Today, July 4, in addition to being the Independence Day of the United States, aphelion occurs. Aphelion is the moment when the Earth is furthest from the Sun, unlike the perihelion that occurred on January 4, when the Earth is closest to the Sun.

Astronomer Johannes Kepler discovered that the orbits of the planets around the Sun are elliptical and that the Sun is not the center of the universe. Because of this elliptical shape, there will always be a point where the Earth is closest to the Sun (perihelion) and another point where it is furthest away (aphelion).

Despite being further from the Sun at aphelion, it is warmer in the northern hemisphere due to the tilt of the Earth’s axis. This causes the Sun to impact more vertically and for more hours on the upper part of the planet.

The maximum distance reached at aphelion is 152 million kilometers between the Earth and the Sun. The average distance is 150 million kilometers, but at perihelion it is reduced to 147 million kilometers.

Both aphelion and perihelion are called apsidal points. According to Kepler’s second law, the translational speed is reduced to a minimum during aphelion, with 103,536 kilometers per hour. At perihelion, the translation speed reaches its maximum, reaching 110,700 kilometers per hour.

Kepler’s second law establishes that the radius vector that joins a planet and the Sun covers equal areas in equal times. During aphelion and perihelion, the radius vector and velocity are perpendicular, this being the only time in which this occurs.

In the southern hemisphere, the seasons are less pronounced due to the lower concentration of continental mass and the greater influence of the moderating effect of the oceans. The aphelion coincides with winter in the southern part of the planet, so temperatures do not rise during this time.

The areas of the globe in which the most rays of the Sun are received during aphelion at noon are the Sahara desert, the Mojave desert, the Arabian desert and the Iranian desert.

Conclude

The Sun moves away from the Earth during winter in the northern hemisphere and during summer in the southern hemisphere. If the Sun smiled, there would be no significant change on Earth. The Sun is estimated to go out in approximately 5 billion years. If the Moon were closer to Earth, we would have more extreme tides and possible changes in climate. When the Sun is furthest from the Earth it is called aphelion. If there were no Sun, life on Earth would be impossible since we depend on its light and heat to survive. On April 23, 2023, no specific event is mentioned. The Sun does not rise at the poles during the polar winter.
