To ensure that the list stays stuck, just think of something along the lines of “Mercury Met Venus Every Night Until Saturn Jumped.” Essentially, this indicates that the size of the planets in order from smallest to largest is Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter.

What are the 2 smallest planets?

Closest to the sun, Mercury is the second smallest planet in our solar system.

What is the smallest thing in the universe?

The electron is, as far as we know, one of the fundamental, indivisible building blocks of the universe. It was the first Standard Model particle ever discovered. Electrons are bound to an atom’s nucleus by electromagnetism.

What is the 3rd largest planet?

Solar System – Uranus. Uranus, the third largest planet in our solar system, may be the strangest because it spins on its side. That severe tilt to its rotational axis may result from a great collision long ago. As the seventh planet from the Sun, Uranus takes 84 years to complete an orbit.

Which planet is near to Earth today?

To find the average distance between Earth & Mars and Earth & Venus, subtract the smaller radius from the bigger one for each pair. The smaller distance gives us the closest planet. That’s Venus!

What is the hottest planet?

Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)

What is the biggest and smallest planet?

The smallest planet in our solar system is Mercury and the largest planet is Jupiter.

Why does Uranus spin backwards?

In 2011, simulations suggested that a number of smaller collisions, rather than one big impact, knocked Uranus’ spin to an angle of 98 degrees. … An alternative explanation put forward by astronomers in 2009 is that Uranus once had a large moon, the gravitational pull of which caused the planet to fall on its side.

Is Earth the third smallest planet?

The second planet in the solar system, Venus, is the third smallest planet with a radius of 3761 miles (6052 km). Earth, of course, is the third closest planet to the Sun and the fourth smallest with a radius of 3963 miles (6378 km). … Mars is the second smallest planet with a radius of 2111 miles (3397 km).

Is Earth a small planet?

Earth is the fifth largest of the planets in the solar system. It’s smaller than the four gas giants — Jupiter, Saturn, Uranus and Neptune — but larger than the three other rocky planets, Mercury, Mars and Venus.
