how does the earth look like from the space?

Venus, Earth and Mars 2020 November 18, seen by the Solar Probe of NASA and the European Space Agency (ESA) (Not connected). This image was taken approximately 155.7 million miles (250.6 million km) away. This is in contrast to the distance between the sun and Earth which is about 150 million km. In this photo, the sun is on the right outside the frame. Image via ESA / NASA/ NRL / Solar Orbita / SolOHI.

how does the earth look like from the space? And … to what extent can we see it with our eyes from Earth?

To find the answer to these questions, let’s take an imaginary journey through the solar system. Spaceships exploring our solar system have given us stunning views of Earth. Read and look at the photos on this page to see what the Earth looks like from various other places in the Al-Space District.

First, imagine an explosion 300 kilometers above the surface of the Earth. This is approximately the height of the International Space Station’s orbit (TKS). Through the window of the International Space Station, the surface of the Earth appears large. During the day you can clearly see the mainland. At night, you see the lights of cities on Earth from Earth’s orbit.

Let’s look further, for example, at the distance of the moon’s orbit.

When we pass the moon, about a quarter of a million miles (about 380,000 km) away, the Earth in space looks like a glowing ball. It’s a little different from the way the moon looks at us.

The first images of Earth from the moon come from the Apollo mission. Apollo 8 1968 was the first human spaceflight to leave Earth’s orbit. It was the first spacecraft on Earth to capture and avoid the gravitational field of another celestial body, in this case the moon.

It was the first journey in which people visited another world and returned to Earth.

Over the decades, as Voyager began traveling abroad, lunar exploration became more and more popular. The Kaguya robotic spacecraft flew around the Earth in 2007. Launched in Japan and officially named SELENE, Kaguya studied the origin and evolution of the moon. The following image is from the Kaguya HDTV built-in camera.

The surface of the moon is riddled with craters, and most of the blue and white Earth has been seen hanging in the black sky above it.

Now let’s go out to see Earth and the Moon together in space. This image was amazing when it was first released. The Earth and moon appear as a crescent, the first of its kind captured by a spacecraft in 1977. September 18

This crescent-shaped image of the Earth and the Moon, the first of its kind, was launched in 1977. On September 18, Voyager 1 captured 11.66 million kilometers from Earth. The moon is at the top of the image and outside the Earth seen by Voyager. Image via NASA.

Since 1977, several robotic spacecraft have landed in our solar system. The mosaic below shows images of the Earth and the Moon obtained by a multispectral photographer on the Asteroids Convergence Vehicle near the Earth (Search for1998 Jan 23, 19 hours after the Earth’s spacecraft tilted toward the asteroid 433 Eros. Two photos were taken at a distance of 400,000 kilometers, roughly the same distance between the two objects.

Earth and the moon were seen by the NEAR spacecraft in 1998.

It is accelerating outward from the Earth-Moon system, passing the orbits of the planets Mars, Jupiter, and Saturn. Of all these worlds, Earth appears as a star, the farthest and weakest.

It is a popular image known as the pale blue point. This is an image of Earth taken in the year 1990. Feb 14 Voyager 1 at a record distance of about 6 billion km. The ground is a bluish white patch around the center of the brown stripe on the right.

The images above are of Saturn, the sixth planet orbiting the sun. I’ve never seen any image of Earth from Uranus, Neptune, or any other object outside of Saturn’s orbit. Only five spacecraft from Earth – the Voyager spacecraft, two astronauts, and the New Horizons spacecraft that overtook Pluto in 2015 – are too far away. This spacecraft was not intended to look at Earth, and as far as I know, has not captured images of Earth from beyond Saturn.

But in theory, can we look at Earth more than Saturn?

Just talk about the earth brightnessThe answer is yes. Our world does not get so dark that we can see it with the naked eye until Neptune passes by, about 14 billion kilometers from our home. Now look at Pluto’s orbit. It has a particularly elliptical shape, ranging from 2.7 billion miles (4.4 billion km) to more than 4.5 billion miles (7.3 billion km) from the Sun. Pluto is located at a finite distance, so if we only consider the brightness, there are no other factors, we should be able to see Earth with the naked eye.

But it is it’s a Another factor. When we leave Earth, our world appears closer and closer to the hot sun. As it recedes, the distant sun begins to darken the view. From Pluto, even though the Earth Sparkly It’s enough to see, you probably can’t see it in the sun.

So here’s the answer How far can the earth be, and you can still see it with your own eyes. Although no one knows exactly why no one has ever experienced it (and because human vision is different from human vision), it may not be possible to see the Earth with the eye somewhere outside of the eye. The orbit of Saturn.

Now let’s change the situation. Suppose we are Maybe Use tools, not just eyes. Suppose you are an intrepid astronautAstronomy scientists He went to Pluto. Let’s say you bring all the tools you need to see the Earth under the sun. Can they use telescopes, hidden disks, and other technologies to see the Earth? Expensive!

But it still won’t be easy.

Conclusion: what does the Earth look like from space? How far can we see Earth with the naked eye in space? according to Exhibition Brightness, the answer is about 9 billion miles (14 billion kilometers), roughly the distance to Neptune or Pluto. In practice, viewing this from such a distance would be difficult, since sunlight would obscure the Earth’s image.
