Earth and Venus are similar because they are formed from the same materials in the solar system. They are close in size and mass. Now how or why are they called “Similar”? Well, it’s because Earth and Venus “ALMOST” have the same size. They have similar density, the same composition (the same material they are made of), and formation. Not only that! Venus is Earth’s closest neighbor.
They also have mountains, plains, volcanoes, and impact craters. Moving on, how are they “Different” at the same time? you see, there’s a planet named “Theia”. This had the same body size as Mars before it collided with Earth, now Theia. It is responsible for Earth’s magnetic field. It was also the reason the moon was created (and might also be the reason how life started on Earth). Venus collided with a planet that caused it to move smaller. The atmosphere on Venus is 100 times thicker than our planet home Earth. Also, the temperature in Venus is extremely hot. Not only that, it rotates backward compared to Earth. The axis also is only about 3° which is so appreciable season there, it is not fit for human life!
Atmospheric Similarity of Earth and Venus
On Venus, deuterium is about 100 times further current than on Earth. They set up it was rich with deuterium — an isotope of hydrogen with a redundant neutron. Deuterium is kindly rare, with about 1 for every 6,500 normal hydrogen titles on Earth. That rate tells scientists about the history of that hydrogen. This indicates to some experimenters that Venus must have formerly had hydrogen most probably in the form of water.

As solar radiation blasted Venus over eons, the lighter, regular hydrogen drifted off into space. Venus and Earth arose near each other within the Sun’s constructive solar nebula. The two worlds must have come from roughly the same structure blocks. In Alien Swell(Springer, 2013), “ Unless some extensively effective process dried Venus out fully, it must have started with more water. It perhaps even an Earth’s ocean’s worth of water — perhaps 10 times this much.
Different Probes and Orbiters explored Venus
But even properly working lens caps caused mishaps. After landing on an alluring geography of a broken fine-graduated, layered gravestone, Venera 14’s lens caps successfully ejected. The hindered panoramic camera saw its cap resting atop plates of interlocking gemstone. But in the frontal view, the cap sounded to have dissolved. Also, shocked flight masterminds spotted it, lying directly beneath the spring-loaded arm that was to probe the soil’s firmness. Sometimes humans contributed some bad luck of their own. During the design of the Venera, Soviet researchers developed advanced paints for 900 F (482 C) heat. These would be placed in the camera’s field of view to calibrate the color images.
Engineers say the power spikes were due to the Pioneer probes’ hardware design. A 1993 NASA report stated, “A failure of sequestration material now explains all anomalous events.” Researchers tested defensive Kapton tape recording in chambers simulating Venus conditions, deeming it acceptable for the wiring on the examinations’ external detectors. However, technicians decided to support using Kynar, a type of shrink tubing. When this tubing reached 620 F( 327 C), it could have released sharp hydrogen fluoride vapors.
Fortunately, answers to this and other mysteries may be at hand in the coming years. Researchers and space agencies are preparing a new wave of Venus missions slated for launch in the early 2030s. These include the European Space Agency’s EnVision orbiter; NASA’s VERITAS orbiter; and NASA’s DAVINCI mission. This orbiter is the first craft to venture into the planet’s clouds since the USSR’s pair of Vega balloons in 1985. To make up for its capricious ways, Venus has bequeathed to humanity information critical for our good.
The Importance of Studying Earth-Venus Similarities
Scientists and policymakers have come to realize that Venus is an important mirror that can help us understand some deep truths about our planet on issues ranging from global warming to the depletion of the ozone layer. It serves as a climate laboratory, an extreme-weather observatory, and a cautionary tale — a bleak example of what could happen to our fragile world. Through its inhospitality, Venus may help us to better manage Earth’s resources and environment, and to avoid changing this temperate world into one more like that of our twin next door. Though Murphy’s law may spare no spacecraft, it doesn’t have to apply to our planet.
