The planets of our solar system orbit in roughly the same plane, which is the plane of our solar system. We can identify the plane of our solar system in the night sky by noting the positions of the planets, which, from our point of view on Earth, appear in a roughly straight line relative to one another. This straight line, which is a cross-section of our solar system, always intersects with the Sun and often with the position of our Moon. On a clear evening after sunset, several planets can often be seen in the western sky forming a line that points directly toward the Sun. Upon finding this alignment, you are looking directly at the plane of our solar system. Check it out! How might this line look different if viewed from the North Pole versus the equator?
