Could this solar system have stable orbits.

In summary, there will be a G2v star with the same mass, radius, and luminosity as our sun, and it will have seven orbiting planets. These planets include one with 0.5 Earth masses at 0.51 au, one with 1 Earth mass at 0.63 au, one with 2 Earth masses at 0.78 au, one with 0.2 Earth masses at 0.85 au, one with 4 Earth masses at 0.95 au, one with 0.3 Jupiter masses at 4.2 au, and one with 0.08 Jupiter masses at 6.5 au. However, the orbital eccentricities must be considered for long-term

I believe you need to know the orbital eccentricities to reasonably assess orbital stability. At a glance, it appears the first 5 planets are just too close together to retain long term stable orbits. Planet 4 is particularly suspect due to its relatively massive and nearby neighbors. N-body calculations are not simple.
 

Related to Could this solar system have stable orbits.

1. What determines the stability of orbits within a solar system?

The stability of orbits within a solar system is primarily determined by the mass and distribution of the objects within the system, as well as the distance between them. The gravitational pull between objects can either cause them to move closer together or push them further apart, depending on their relative positions and masses.

2. Can a solar system have multiple stable orbits?

Yes, a solar system can have multiple stable orbits. In fact, most solar systems in our universe have multiple objects orbiting around a central star. As long as the objects are properly spaced and their masses are balanced, they can maintain stable orbits without colliding or being ejected from the system.

3. What is the role of the central star in maintaining stable orbits?

The central star plays a crucial role in maintaining stable orbits within a solar system. Its mass and gravitational pull help keep the other objects in orbit and prevent them from drifting away. The size and distance of the central star also determine the habitable zone, which is the area where planets can maintain stable orbits and support life.

4. Are there other factors that can affect the stability of orbits in a solar system?

Yes, there are other factors that can affect the stability of orbits in a solar system. For example, the presence of other nearby stars or massive objects can disrupt the orbits of objects within the system. Additionally, collisions or close encounters between objects can also lead to changes in their orbits.

5. Is it possible for the orbits within a solar system to become unstable over time?

Yes, it is possible for the orbits within a solar system to become unstable over time. This can happen due to various factors, such as changes in the mass or position of objects within the system, as well as external influences from other celestial bodies. However, most solar systems are able to maintain relatively stable orbits for long periods of time.
