Simulations show that the stars’ tug could send Mercury, Venus or Mars crashing into Earth — or let Jupiter eject our world from the solar system.

Figure 1: The inner Solar System and outcomes of simulations of its formation. Although planets follow nearly circular, co-planar orbits, asteroid orbits are much more elliptical, and can be ...

The gravity of the Sun pulls planets toward the center of the solar system. The inertia from the creation of the planets sent them flying in a straight line, perpendicular to the force of the Sun’s ...

Additionally, such moons, called regular moons, follow nearly circular paths that share a plane with the planets' equators. You may like How many moons are in the solar system? Saturn gains 128 ...

This may explain the strange properties of the orbits of our solar system's planets, which are not quite perfectly circular, and all lie on slightly different planes. NASA artist’s conception of ...

OK, let's review. The solar system started from a slightly rotating cloud of dust. Particles near the equator found a stable circular orbit as the inward-pulling gravitational force was balanced ...

Gravity is the force that governs the structure and motion of the solar system, keeping celestial ... that the paper assumes that all orbits are circular, whereas real bodies are not perfectly ...
