What Is The Second Smallest Planet

Mars is the Solar System’s second-smallest planet, with a diameter of 6792 kilometers. With all of the attention and exploration paid to Mars, you’d assume it’s a massive planet, but it’s quite little. Mars is just 53% the size of Earth and weighs approximately a tenth of its mass.

The Difference Between Mars and Earth

Here’s a 5-minute video that simplifies the difference between Mars and Earth.

Mars has an extremely low gravitational force since it is so small compared to Earth and has only a fraction of Earth’s mass.

If a person could walk on Mars, you’d only feel 38% of the force of gravity that pulls you down here on Earth. If you weighed 100 kilograms on Earth, you would only weigh 38 kilograms on Mars.

Because Mars is so small, its core cooled billions of years ago, and it no longer has a magnetic field. The Earth’s magnetic field aids in the pushback of the Sun’s solar wind, attempting to pull our atmosphere away.

When you combine this with its extremely low gravity, Mars has lost nearly all its atmosphere. In fact, Mars’ atmosphere has 1% of what we have on Earth.

FAQs

What is Mars like today?

Mars is inhospitably cold, with a typical -63° C (-81° F). The planet’s atmosphere is 95.3 percent carbon dioxide, and the Sun’s radiation bombards its surface because it lacks a magnetic field.

Warmer months highs often reach 30°C (86° F), but it’s still no picnic. The planet’s atmosphere is 95.3 percent carbon dioxide, and the sun’s radiation bombards its surface because it lacks a magnetic field.

What was Mars like in the past?

Mars wasn’t always so barren. It’s believed that Mars had a molten core that emitted a magnetic field once upon a time. As a result, the planet’s surface was covered with radiation, and a thicker atmosphere kept the planet warm.

There is also significant evidence that Mars had water on its surface approximately 3 to 4 billion years ago.

Scientists have discovered river-carved valleys, stream-formed pebbles, and sediment piles that could have originated from basins and deltas. Life might have been possible under these circumstances.

Is Mars hotter or colder than Earth?

The temperature on Mars is significantly colder than on Earth. However, the planet is further away from the sun.

The thin atmosphere of the little, arid planet is 95% carbon dioxide. It’s a harsh and chilly environment with temperatures below 200 ℉ due to several variables.

Is Mars habitable?

Mars’ atmosphere is mainly carbon dioxide, and the planet’s surface is too frigid for human life. In addition, the planet’s gravity is just 38% that of Earth. More so, Mars’ atmosphere is only 1% of the atmosphere on Earth at sea level.

Laura Kerber once said, “Apart from Earth, Mars is the most livable planet in the solar system.”

She added, “However, many forms of life continue to face a harsh environment. A technology for constructing small habitable islands on Mars might allow us to modify the planet in a regulated and scalable manner.”
