Yes, true.
No, not all planets have elliptical orbits. While most planets in our solar system have nearly circular orbits, some planets, like Mercury and Pluto, have more elliptical orbits. Additionally, exoplanets outside our solar system can have a variety of orbital shapes.
The circular orbits that were being used at the time to model the solar system did not quite work with mathematical predictions or observations. Kepler found that elliptical orbits provided more accurate predictions of where the heavenly bodies would appear in the sky.
The Earth's orbit around the Sun is more circular and consistent, while a comet's orbit is typically more elliptical and variable. Comets also come from the outer solar system and have highly eccentric orbits that can bring them close to the Sun, leading to the development of a bright coma and tail due to the heat and radiation.
NO!!! The planets do NOT orbit in circles. They orbit the Sun in an ellipsoidal manner. An ellipse has two foci. The Sun lies at one of the foci, the other might be deemed to be a 'blind' focus. The Sun does NOT lie at the centre of the ellipse. Also the satellites(moons) orbit their parent planets in a similar manner. It has also been discovered that the planets in an an ellipsoidal manner. That is as each orbit is completed the planet 'over-shoot' their starting point, and the ellipse does not close . See Johannes Kepler, who gave us the Law of orbiting planets sweeping equal arcs in equal times , in 1602 AD.
There are no solar system orbits that are perfectly circular, because all have at least a slight change in orbital distance as they circle the Sun (eccentricity). For Mercury and Pluto, the different between the closest and farthest points is fairly large, while for Earth it is much smaller.
Yes some elliptical orbits are more circular than others
An ellipse is a closed curve that is not circular (the curve is not a constant distance from any point inside of the curve). While some planetary orbits are relatively circular, others are more elliptical, that is having an oval shape with a varying distance from the Sun.
Yes, none of the planets in our solar system have exactly circular orbits, though some are more eccentric than others.
The veracity of that conjecture can't be disputed.
Comets typically have elliptical orbits, which means their paths around the Sun are elongated and not perfectly circular. This is due to the gravitational influence of other celestial bodies, causing their orbits to be more elongated.
variation in distance between the planet and the sun over the course of its orbit, compared to more circular orbits. This can lead to more extreme temperature fluctuations on the planet's surface and potentially affect its climate.
No, not all planets have elliptical orbits. While most planets in our solar system have nearly circular orbits, some planets, like Mercury and Pluto, have more elliptical orbits. Additionally, exoplanets outside our solar system can have a variety of orbital shapes.
The planets in our solar system orbit the Sun in elliptical paths, which are elongated circles. These orbits are shaped by the gravitational pull of the Sun and the planets themselves, following Kepler's laws of planetary motion.
A typical planet's orbit is often elliptical, meaning it is elongated with one focus at the center. The degree of elongation can vary, with some orbits being more circular and others more eccentric.
Asteroids generally have more eccentric and inclined orbits compared to planets, which typically have more circular and aligned orbits. Asteroids can intersect the orbits of planets and have a wider range of distances from the sun. Planets, on the other hand, tend to orbit in a more stable and predictable manner.
Pluto does not behave like the other planets in our solar system because it has a highly inclined and elliptical orbit. This means that its path around the Sun is very different from the near-circular and more closely aligned orbits of the eight traditional planets.
You can determine which of two orbits is most elliptical by comparing the eccentricities of the orbits. The orbit with the higher eccentricity is more elliptical. Eccentricity measures how stretched out an orbit is, with a value of 0 indicating a perfectly circular orbit and a value closer to 1 indicating a highly elliptical orbit.
