Is Mars the closest planet to the Earth?

Among the eight planets in the solar system, we have always been most concerned about Mars, because scientists unanimously regard Mars as the future immigration target, and we are also concerned about the moon, Jupiter and Mercury. But in fact, the closest planet to the earth is Venus, which is almost ignored compared with the moon and Mars. Even mercury, which is smaller and farther than it, has attracted everyone's attention because of its "closest to the sun". So what kind of planet is Venus?

In fact, this low attention to Venus is only because it has no clear focus. However, scientists have been paying attention to Venus. The United States and Russia plan to implement a cooperation plan for large-scale exploration projects in 2025. In fact, attention to Venus began with the probe Venus 19 1 launched by the former Soviet Union in 1, and scientists never stopped exploring it. 1967, the landing probe Venus 4 was successfully launched, but the pressure and temperature exceeded expectations, resulting in the damage of the probe.

Other Venus probes had various problems, but soon, in 1970, the year when China launched "Dongfanghong 1", the Soviet "Venus 7" successfully landed on the surface of Venus and returned the first batch of data. Later, the Venus program of the Soviet Union continued until 1985. After Venus 16, two Vega probes were launched. American detectors are mariner series detectors and pioneer Venus detectors in the same period, and the most famous one is Magellan detector.

In addition, the European Space Agency and Japan also explored Venus. The Venus Express of the European Space Agency is the first probe launched by the European Space Agency on Venus. It was launched in 2005, five years before the Japanese Dawn.

The exploration of Venus by "Venus Express" gave scientists a deep understanding of the geological conditions of Venus, but the Japanese "Dawn" was not smooth. After the launch of 20 10, Dawn quickly approached Venus, but failed to enter orbit successfully. It was not until 20 15 that it successfully entered Venus orbit.

Now the Venus projects in Russia and the United States will once again explore Venus in depth. If we can make a thorough study of Venus, perhaps Venus will become one of the immigration options for the earth in the future. After all, Venus is the closest planet to the Earth, and it lands much faster.
