How far is the distance from Earth to Mercury?

Mercury ( Mercury ) is a planet located near the Sun and takes a little time to spin around the most massive star. Because of its proximity to Mercury, our Earth's temperature is often high and it is difficult to maintain the atmosphere.

Mercury or Mercury is the planet with the most elliptical orbit in all the planets, it is stretched from a circle. The closest distance to the Sun is 47 million km and the farthest distance to Mercury is 70 million km. Although Pluto 's orbits are more eccentric than Mercury , Mercury is the " elliptical orbit " because of the large miniature " body " into a dwarf planet, the miniaturization of Pluto makes Mercury the smallest of 8 solar planets .

This " strange " trajectory initially embarrassed astronomers in trying to put pieces together so that the Solar System could work. When Mercury is located farther away from the Sun , it will be the slowest moving planet. This means that the Earth takes three months and 15 days to keep up with Mercury . Astronomers analyze the motion chart of Mercury in the sky, showing a slow movement every night through each stage related to other stars in the sky. Not until the great astronomer Nicolaus Copernicus studied: "The planets go around the Sun , not around the Earth . "

Ironically, although Mercury is the closest planet to the Sun , it is not the hottest planet and Venus is the hottest planet. Only in thin air does the water change the temperature constantly to keep the planets cool, while Venus 's atmosphere creates a greenhouse effect that makes it easier to raise the temperature higher than stars Thuy .

Because Mercury is so close to the Sun , the Hubble Space Telescope has captured important images of the solar system , but unfortunately does not capture the rock surfaces of the planets.

On May 9, 2016, Mercury passes through the Sun's surface - a rare sight that impresses observers around the world. The image below gives an overview of Mercury during the seven-and-a-half-hour event observed at NASA 's Solar Dynamics Observatory Observatory .

Mercury and the Sun.

Mercury is located between the Earth and the Sun, so it must go through the same stages as the Moon . However, Mercury 's stages are more difficult to detect than Venus 's stage - Venus's orbits also rotate between Earth and the Sun. Italian astronomer - Galileo Galilei studied the stages of Venus with telescopes - that is not the stage of Mercury .

Like Venus , Mercury also goes through the period between Earth and the Sun about 13 times in a century. But Mercury 's orbital inclination is the irregular movement that occurs between the two planets. Mercury only passes through the Sun every seven years. Astronomers used this movement to calculate the distance from the Sun to Earth . The phenomenon of Kim pond crossing the Sun is even rarer, only happening once every 243 years. During that time, there were three spacecraft observing the movements of the planets.

Joseph GURMAN said in a report: " It is difficult to observe the passing movement. For example, if you are in a place with bad weather, you will miss the opportunity and have to wait. Next opportunity ". Gurman conducts scientific research for NASA's Solar Energy Project ( SOHO ) - just one of the tools needed. NASA's Solar Dynamics Observatory and Japan's Hinode aerospace exploration mission also capture Mercury passing through the Sun.

Gurman said: " These devices have supported our observation very much despite experiencing any obstacles on Earth ."

The distance between Earth and Mercury?

The constant movement of planets orbiting the Sun means that the distance between Earth and Mercury also changes constantly. When the two planets lie on either side of the Sun, they can reach a maximum distance of 222 million kilometers. And when the two planets are closest to each other, the distance between them is only 77.3 million kilometers.

How long does it take to get to Mercury?

Mercury is not as far away as other planets, but only a few spacecraft can reach it. To go to a planet is not the same as how we drive everyday. Engine improvements are not the most important factor to decide how long it will take. Space agencies often use large gravity from other planets to achieve speed without losing high material costs. Unlike a trip, the starting and ending point of the solar system can change positions continuously, sometimes traveling the same way but losing different time periods.

NASA's Mariner 10 revolved around Venus to arrive at Mercury, which was released on November 3, 1973. And on March 29, 1974, the first flight made by a spaceship took just over four months to get. Can reach planet Mercury. Mariner 10is the first two spacecraft to fly to planets and get gravity.

The hot stone blocks that have been exploited have not been set yet by any astronaut. On August 3, 2004, NASA released the image of Mercury Surface, Aerospace, Geochemistry and Mission ( MESSENGER ) in planets. MESSENGER tested a space aircraft to Earth and two Venus before heading to Mercury on January 14, 2008 - a journey lasting nearly three and a half years.

The European Space Agency and the Japanese aerospace agency have sent a joint plan on a trip to Mercury with the BepiColombo spacecraft. The plan will be implemented in 2018, the spacecraft will fly to Earth once and Venus twice to reach Mercury in 2024 - the space trip will last six and a half years.
