Can we see Mars from Earth? What does the mysterious veil of Mars mean?

People don't know much about Mars and have never been to it, calling it a "mysterious veil". The closest distance between Earth and Mars is more than 55 million kilometers. When Mars is closer to Earth, we can see Mars with our naked eyes on Earth. How long does it take to go to Mars? Let's find out together!

Can you see Mars from Earth?

The distance between Earth and Mars is different. The closest distance is about 55.7 million to 120 million kilometers, and the farthest distance is about 400 million kilometers. When Mars is closer to Earth, we can see Mars with our naked eyes on Earth.

Mars is one of the eight planets in the solar system. It is the fourth planet from the inside to the outside of the solar system. It is a terrestrial planet with a diameter of about 53% of the Earth and a mass of 11% of the Earth. Its axial inclination and rotation period are similar to those of the Earth, and its orbital period is about twice that of the Earth. The orange-red surface is hematite (iron oxide) on the surface. In ancient Chinese books, Mars was called "Yinghuoxing" and in ancient Western (ancient Rome) it was called "Mars, the God of War".

Mars is basically a desert planet, with sand dunes and gravel all over the surface and no stable liquid water (on September 28, 2015, NASA announced that there is a small amount of water on Mars). The atmosphere, which is mainly composed of carbon dioxide, is both thin and cold, with sand and dust suspended in it, and dust storms often occur every year. There are polar caps composed of water ice and dry ice at both poles of Mars, which grow and decline with the seasons.

What does the mysterious veil of Mars refer to?

The "mysterious veil of Mars" does not refer to a specific thing, but means that people do not understand Mars and have never come into contact with it, so they call it the "mysterious veil."

How long does it take to go to Mars?

1. The distance between the Earth and Mars is more than 55 million kilometers at the closest, and 300 to 400 million kilometers at the farthest. The speed of light is 300,000 kilometers per second, so if it is light, the closest distance from the Earth to Mars is 150 seconds, and the farthest distance is more than 1,000 seconds, which is about 20 minutes!

2. If humans were to go to Mars by spacecraft, it would take 7 to 8 months according to current technology, and of course, they would fly there when Mars is at its closest distance to Earth, more than 55 million kilometers away. A round trip to Mars would take at least 2 to 3 years.
