Oh, an interesting question! Mercury's semimajor axis - which is the distance from the center of the Sun to the farthest point of Mercury's orbit - is about 0.39 astronomical units, or around 57.9 million kilometers. That's a nice and cozy space for our little Mercury to dance gracefully around the warm Sun. Nature has a way of creating beauty in all the details like this, doesn't it?
The semimajor axis of a planet's orbit is important because it determines the size and shape of the orbit, as well as the distance of the planet from the sun. It helps us understand the planet's position in relation to the sun and other planets, and provides valuable information about the planet's orbital characteristics.
The orbit of a planet is the path it follows as it travels around the sun. The axis of a planet is an imaginary line running through its center and around which it rotates. The tilt of a planet's axis relative to its orbit affects its seasons.
Ah, the average distance from the sun to the planet Mars is about 225 million kilometers, my friend. Just imagine Mars floating peacefully in space, soaking up the sun's warm glow on its journey around the solar system. Isn't that just a happy little fact to ponder? Remember, in our universe, every planet has its own special place.
It does NOT orbit on its axis, but rotates on its axis. It takes 24 hours, one day, to make one complete rotation. However, It does ORBIT the Sun. It takes the Earth 365.25 days, one year, for make one complete orbit of the Sun. Whilst it is making this orbit it is also rotating on its axis, as above.
The Earth stays in orbit around its axis due to its rotation and inertia. The gravitational pull of the Sun keeps the Earth in its orbit, while its rotation on its axis causes day and night. The tilt of the Earth's axis also plays a role in the changing seasons.
Using Kepler's third law, the period (P) of an object in orbit can be calculated using the formula P^2 = a^3, where a is the semimajor axis in astronomical units (au). For Ceres with a semimajor axis of 2.77 au, the period of its orbit around the Sun is approximately 4.61 years.

The period revolution of an orbiting body is directly related to its semimajor axis through Kepler's Third Law of Planetary Motion. This law states that the square of the orbital period (T) of a planet is directly proportional to the cube of the semimajor axis (a) of its orbit, expressed mathematically as T² ∝ a³. This means that as the semimajor axis increases, the orbital period increases as well, indicating that objects further from a central body take longer to complete an orbit.
One of the parts of an ellipse is the length of its major axis. Half that is called the semimajor axis. Kepler's 3rd law says that the time to do one orbit is proportional to the 3/2 power of the semimajor axis. IF the semimajor axis is one astronomical unit the period is one year (the Earth). For a planet with a semimajor axis of 4 AUs the period would have to be 8 years, by Kepler-3.

Mercury has the smallest orbit. The semimajor axis of Mercury's orbit is about 58 million kilometers, which is the smallest of all of the planets.
(I'm going to assume that when you said "first" you meant "fastest," because otherwise the question is nonsense.) Because of Kepler's Third Law. The orbital period for a body is related to the semimajor axis of its orbit. Mercury's orbit has the shortest semimajor axis of all the Solar planets, and therefore it has the shortest orbital period.
The major axis is the diameter across the widest part. The semimajor axis is half that, and for a planet it's the average of the maximum and minimum distances from the Sun .
An orbit with a large semimajor axis will have the longest period according to Kepler's third law. This means that an orbit with the greatest average distance from the central body will have the longest period.
The major and minor axes of a circle are the same - either is any diameter. So a semimajor axis is half the diameter which is 12 cm.
the period of revolution is related to the semimajor axis.... :)
The period of revolution can be calculated using Kepler's Third Law: P^2 = a^3, where P is the period in years and a is the semimajor axis in astronomical units (AU). In this case, the period of revolution of the planet would be approximately 4.00 years.
