The Largest Planetary System that Could Exist

The video explores the boundaries of the solar system, focusing on the Voyager missions and their journey into interstellar space. It explains the concept of the heliopause and the Hill sphere, which defines the true edge of the solar system. The video also discusses the Oort Cloud and the potential size of solar systems, considering gravitational influences and theoretical limits.

What is the heliopause?

• The boundary where the Sun's magnetic field is overcome by interstellar wind

• The edge of the solar system defined by gravitational influences

• A region containing icy bodies and comets

• The orbit of Pluto

What defines the true boundary of the solar system?

• The Sun's Hill sphere

• The Kuiper Belt

• The orbit of Pluto

• The heliopause

How does the Sun's Hill sphere vary in different directions?

• It is the same in all directions

• It is influenced by nearby stars and their gravitational pull

• It is determined by the solar wind

• It is perfectly spherical

What is the Oort Cloud believed to contain?

• Stars and galaxies

• Asteroids and meteors

• Icy bodies and long-period comets

• Planets and moons

How long would it take Voyager to reach the beginning of the Oort Cloud?

• 1 million years

• 1300 years

• 10,000 years

• 100 years

What is the theoretical limit of a star's mass?

• 150 solar masses

• 100 solar masses

• 50 solar masses

• 300 solar masses

Under what conditions could a solar system be as large as a galaxy?

• If the star is surrounded by a large number of planets

• If the star is part of a binary system

• If the star is isolated with no nearby gravitational forces

• If the star is in a densely packed cluster
