Mercury.
Yes, gravity is what determines the shape of a planet's orbit around a star. Depending on the initial conditions of the planet, the orbit can be circular, elliptical, or another shape, but gravity is always the force that governs the path of the planet.
False. The shape of the orbit of each planet is an ellipse, not a perfect circle. This is described by Kepler's First Law of Planetary Motion, which states that planets move in elliptical orbits with the Sun at one of the foci. While some orbits may appear nearly circular, they are not perfectly circular.
No planet's orbit is perfectly circular. They are all elipses.
The orbits of planets are actually elliptical, not perfectly circular. An ellipse is a stretched-out circle. The shape of a planet's orbit can be described as an ellipse with the Sun at one of the two foci.
No planet has a perfectly circular orbit, though Venus has the least orbital eccentricity of any planet in our solar system.
An eliptical orbit. In theory a planet could also have a circular orbit, but no planet that we know of has a perfectly circular orbit, although some have a nearly circular orbit.
Not all celestial bodies move in circular orbits around larger objects. Planets can also orbit around stars or even on their own. So, it is not a requirement for a planet in a circular orbit to be moving around something bigger.

an orbit is the circular movement of a planet going round the sun, or a moon going round a planet. Gravitaional force is what creates the orbit.
The magnitude of a planet's velocity affects the shape and size of its orbit. A higher velocity can cause a planet to move in a more elongated elliptical orbit, while a lower velocity can result in a more circular orbit. The velocity also influences the planet's escape velocity, which determines if it can break free from its orbit.
When a planet or moon moves in a circular pathway around something else, such as a star or planet, it is in orbit. The gravitational pull between the objects keeps them in motion and prevents them from floating off into space. This movement is governed by principles of celestial mechanics, particularly Kepler's laws of planetary motion.
If the speed around the sun decreases, the orbit will become more elongated and the planet will move farther away from the sun. If the speed increases, the orbit will become more circular and the planet will move closer to the sun. This change in speed can affect the length of the planet's year and the temperatures experienced.
A planet in an elliptical (oval) orbit will move faster as it gets to its closest point to its sun, and slow down as it reaches its furthest point. A planet with a truly circular orbit will have a constant speed.
False. The shape of the orbit of each planet is an ellipse, not a perfect circle. This is described by Kepler's First Law of Planetary Motion, which states that planets move in elliptical orbits with the Sun at one of the foci. While some orbits may appear nearly circular, they are not perfectly circular.
Currents move in a circular patteren because of the strong wind on planet earth.
