Planets' orbits are all forms of conic section, the curve formed by intersecting a plane with a symmetrical circular cone.
The shape of a conic section is defined by a parameter called eccentricity, written as e. In order of eccentricity the four orbital shapes are: circles (e=0), ellipses (0<e<1), parabolas (e=1) and hyperbolas (e>1). Planets' orbits are ellipses with e less than 0.1, so they are approximately circular. You can only get a hyperbolic orbit with a body coming in at high speed from outside the solar system, which is extremely rare.
You can make conic sections by shining a torch on a wall (a torch with a old fashioned bulb, not LEDs). It produces a cone of light, and the wall gives the intersection, so on the wall you can create those four shapes. Shining it straight at the wall gives a circle, slightly off gives an ellipse, then with one side of the cone parallel to the wall you get a parabola, and turning it further creates a hyperbola.
What else can I help you with?
Are all planets and stars shape like circle?
All planets and stars are approximately spherical in shape, a shape formed under their own gravity. Most are `oblate` spheroids though, squashed spheres, since their rotation can cause them to `bulge` out at the equator if it is sufficient enough.
What is the shape of all 8 planets in our solar system?
The 8 planets in our solar system are mostly spherical in shape due to their gravitational forces pulling them into a roughly spherical form. However, factors such as rotation and composition can lead to some variations in shape.
What are inner planet shapes?
The inner planets (Mercury, Venus, Earth, Mars) in our solar system are all roughly spherical in shape due to their gravity compressing their material into a spherical form. They lack the mass to maintain a more irregular shape like some larger moons or asteroids.
What is the shape of the outer planets?
Planets don't revolve around the Earth.Planets revolve around the Sun in ellipses.
What is the shape of a planets obit?
ellipitcal
What are the characterstics of Planets?
all planets have a circular shape
What is the typiccall shape of the planets?
Planets are all spherical.
What shape are planet?
The inner planets have a spherical shape. In fact all planets are more or less spherical.
Which planets orbital shape is similar to Jupiter?
All planets in our solar system have elliptical orbits.
Is there a planet that is a rectangular shape?
No all planets are almost perfect spheres
What is the shape of Neptune's path?
all of the planets have the same elliptical shaped orbit.
What is the shape of a planets orbit and in which direction do all planets revolve?
Planets orbit in an elliptical shape around the Sun, with the Sun located at one of the foci of the ellipse. All planets in our solar system revolve counterclockwise when viewed from above the Sun's north pole.
Are all planets and stars shape like circle?
All planets and stars are approximately spherical in shape, a shape formed under their own gravity. Most are `oblate` spheroids though, squashed spheres, since their rotation can cause them to `bulge` out at the equator if it is sufficient enough.
What is the shape of all 8 planets in our solar system?
The 8 planets in our solar system are mostly spherical in shape due to their gravitational forces pulling them into a roughly spherical form. However, factors such as rotation and composition can lead to some variations in shape.
What is the shape of neptue's orbit?
As with all the planets, the orbit of Neptune is a nearly circular ellipse.
What shape do you think the universe is?
Since all of the planets, and moons, and stars seem to have a spherical shape, it is possible that the universe may be a sphere.
Which planets has more of a spherical shape?
There are two planets with an almost perfectly spherical shape. They are Mercury and Venus.
