Three dwarf planets?
The solar system has three classified dwarf planets. They are Pluto, Ceres, and Eris. A dwarf planet has sufficient mass, has not cleared the neighborhood around its orbit, and is in orbit around a star.
What are three ways that the outer and inner planets are alike?
Shape, rotation-direction, and orbit-direction.
Why is the earth's orbit an ellipse?
Due to gravitational forces by other planets in universe,earth changes its circular orbit into ellipse.it has enough tangential velocity to leave the orbit and go straight,but sun attracts it and vice versa.
Did the planets align on Wednesday march 10th?
No, the planets did not align on Wednesday, March 10th. Planetary alignments occur when the planets in our solar system appear in the same part of the sky from our perspective on Earth, but true alignments are quite rare.
In what ways are the moons stars and planets interrelated?
Moons are natural satellites that orbit planets, planets orbit stars like our Sun, and stars are part of galaxies that contain planets and moons. Moons are gravitationally bound to planets while planets are gravitationally bound to stars. All three are part of the same interconnected celestial system.
Why is Pluto different from the other planets?
Since it was discovered in 1930 by Clyde Tombaugh, many astronomers have felt uneasy about Pluto being called a "planet" for three reasons: (a) Pluto, with a diameter of 2275 km, is very much smaller than any of the other planets of the Solar System; in fact, it is only about two-thirds the size of our Moon. (b) Its highly elongated orbit is greatly tilted at a sharp angle to the orbital planeof the other planets; in other words, all the other planets revolve around the Sun at almost the same plane. (c) Furthermore, it is the only planet with an orbit that intrudes to the orbit of another planet (that of Neptune).The other outer planets are very large and gaseous. Pluto is very small, and doesn't have as much gas.
What are three rules for consideration for planets?
Three rules for consideration for planets are: 1) The planet must orbit a star. 2) The planet must have enough mass to have a nearly round shape. 3) The planet must have cleared its orbit of other debris.
Do all the planets orbit around the earth or sun?
All planets orbit around the sun in our solar system. The sun is at the center of our solar system, and its gravitational pull keeps all the planets in orbit around it. The idea of all planets orbiting around the Earth was a historic belief known as the geocentric model, which has been proven incorrect by modern astronomy.

What is the three main parts of solar system?
The three main parts of the solar system are the Sun, which is the central star that all other objects orbit around; the eight planets, which include Earth, Jupiter, and Mars; and various smaller bodies such as asteroids, comets, and moons that also orbit around the Sun.
Is earth larger or smaller than all the other planets?
Of the seven other planets that orbit the sun, three are smaller than Earth and four are larger.
Is there any time of the year when all the planets are in line with each other?
No, usually the planets are in different directions. Every few years two or three of them line up.
What three things along with the planets and their moon orbit the sun?
satilites

What is the orbit of planets?
The orbit of each planet it the path it takes as it rotates round the Sun under the influence of the force of gravity. Every planet has a separate orbit and the orbits all follow Kepler's three laws of planetary motion.
What three factors determine planets in the solar system?
1) An object orbiting the Sun 2) Having a Radius of over 2000 kilometers 3) Has cleared it's orbit environment from other objects.
