What do you think would happen if the planet didn't travel in orbit around the sun?

If the planet didn't travel in orbit around the sun, it would likely drift through space, losing the stable conditions necessary for life as we know it. Without the sun's gravitational pull, Earth would not experience the consistent cycles of day and night, nor the seasonal changes that are crucial for ecosystems. The absence of sunlight would lead to drastic temperature drops, rendering the planet inhospitable and freezing most life forms. Ultimately, Earth's environment would become unlivable, severely impacting all biological processes.
