![]() The Terrestrial planets formed later from heavier elements spit out of the sun as a result of fusion. The Jovian planets formed at the same time as the sun from the gas and dust in the nebula. The Jovian planets formed in the outer part of the disk where the hydrogen and helium were moving fast enough to escape the pull of the proto-sun.Į. ![]() As the protostar formed in the middle of the disk, it pulled all of the hydrogen and helium out of the inner part of the solar system. apparent magnitude gives us an idea of the stars apparent brightness, how bright the star appears to be from Earth, at its true distance, D. This novel by James Lecesne, the cofounder of The Trevor Project, inspired the critically-acclaimed Off-Broadway show The Absolute Brightness of Leonard Pelkey. The Jovian planets formed from the leftover material from the gas cloud that formed the sun, while the inner planets were interstellar wanderers that were captured as the sun orbits around the center of the Milky Way.ĭ. The less dense material stayed further away.Ĭ. The absolute brightness or magnitude of an object is the apparent brightness or magnitude it would have if it. There was more gravitational force on denser material, so it ended up closer to the sun. A measure of the true brightness of an object. Further away, low density material solidified.ī. Near the sun, only rock and metal were solid. This works by imagining we could place every object in the sky at a. This novel by James Lecesne, the cofounder of The Trevor Project, inspired the critically-acclaimed Off-Broadway show The Absolute Brightness of Leonard Pelkey. Absolute magnitude is a similar measure that represents how bright an object actually is. The outer planets are much more massive and much lower density than the inner planets. Phoebe, her family, and her community fight to understand what happened, and to make sense of why someone might want to extinguish the beautiful absolute brightness that was Leonard Pelkey.
