Question

the solar system and nearby stars are part of a much larger structure, the milky way galaxy. the milky way, like many other galaxies, contains billions of stars and planetary systems. these objects orbit around the galaxys center, a supermassive black hole over four million times as massive as the sun! this black hole has an extremely strong gravitational influence, even on objects that are incredibly far away. the sun and the rest of the solar system orbit the milky ways center from over 25,000 light - years away.
the immense gravity of the milky ways central black hole, as well as gravitational attractions between massive objects within the milky way, help hold the entire galaxy together.
select the true statements.
there is a supermassive black hole at the center of the solar system.
gravitational forces hold the entire milky way galaxy together.
the solar system is the only planetary system in the milky way galaxy.
the sun is at the center of the milky way galaxy.

Explanation:

• Analizar cada afirmación:

• "Gravitational forces hold the entire Milky Way galaxy together": El texto dice "The immense gravity... help hold the entire galaxy together". Correcta.
• "The solar system is the only planetary system in the Milky Way galaxy": El texto dice "contains billions of stars and planetary systems", así que no es el único. Incorrecta.
• "The Sun is at the center of the Milky Way galaxy": El Sol orbita el centro de la Vía Láctea, no está en el centro. Incorrecta.
