This may appear so from a Solar System perspective. The degrees of inclination range from 3.38 degrees for Mercury to Earth (which has the largest) with 7.55 degrees of inclination from the Sun's equator.
Nothing special.
Its called the catastrophic alignment or planetary alignment
Yes. If it is not straight, then it is not a line.
If it is not straight, then it is not a line.
it just a straight line
Inertia is the tendency of objects to keep moving in a straight line. They "want" to go in a straight line, so to speak. However that is changed when a force acts on them. In the case of planets, that force is the gravitational force between the planet and the Sun.So that's why planets orbit the Sun instead of traveling in a straight line.
Nothing special.
Straight line through 3 planets such as Sun, Earth and Moon
Newton
The force of gravity.
They never did. In all the solar systems history, all 8 planets never alighned in a straight line
Kepler's Law: "The orbits of the planets are ellipses with the Sun at one of the foci."
It's not that there is some force keeping the planets from falling into the sun; the sun's gravity prevents the planets from travelling in a straight line out of the solar system. If you throw a ball in a straight line then it keeps going, but if you throw a ball on a rope tied to a pole then the rope pulls the ball toward the pole and keeps the ball moving in a circle.
The natural motion of the planets is motion in a straight line. They are prevented from straight line motion by the gravitational force of the Sun.
The sun moves in straight line and the planets move around it in spiral way
Its called the catastrophic alignment or planetary alignment
Gravity is what keeps the planets going in their orbits. If gravity just stopped, then the planets would go flying in a straight line tangent to their orbit.
