![]() ![]() ![]() Jupiter is the just-right size, the just-right distance from Earth, the just-right mass and is in the just-right location to shield Earth from being regularly bombarded with comets and asteroids deadly to life. Įarth Has a Just-Right Sister Planet ( Jupiter) Earth orbits a single star system which is the only kind of star system that can support life. Notably, excluding white dwarfs, stars are in a binary and multi-star system. Life is also not possible on a planet that orbits a binary star system or a multi-star system because the gravitational forces exerted on the planet by the additional stars would frequently pull the planet out of a temperature zone where life could exist. Consequently, life is not possible on a planet that does not orbit any star because the planet would be too cold and too dark to support life. To support life, a planet must be able to provide sufficient heat and light. The Size of the Sun Relative to Earth more>Įxample No. The sun has the just-right mass to allow it to provide Earth with a stable environment with sufficient amounts of light and heat that can support life. Indeed, if the sun were the size of a basketball, then, comparatively, the earth would be less than the size of a ball bearing used in a BB gun. In comparison to Earth, the sun is very massive. But, if Earth was closer to the sun, the sun would exert so much gravitational force on the earth that it would cause Earth’s rotation period to slow down causing one side of the planet to get too cold and the other side to get too hot to support life. If the sun were less massive, Earth would have to be closer to the sun in order to get enough heat to support life. ![]() 1 - Earth’s Sun has a Just-Right MassĪ star more massive than the sun would burn too quickly and too erratically to support life on any planet in the solar system. Earth’s parent star, the sun, has all 140+ characteristics, including the following two examples:Įxample No. In order for a planet to be capable of supporting life, it must orbit a star (called its parent star) and the parent star must have all 140+ finely-tuned features scientists have discovered a parent star must have in order for the orbiting planet to be able to support life. Without all of the just-right features, Earth would not be capable of supporting life.Įarth Has a Just-Right Parent Star (the Sun) Earth resides in a just-right solar system which, among hundreds of other features, has: In order for a planet like Earth to be capable of supporting life, the planet must reside in a just-right solar system with the hundreds of just-right features necessary to support life on the planet. Not only is Earth located in a just-right location within a just-right galaxy ( here >) in a just-right universe ( here>) that operates under the just-right laws of physics ( here >), Earth is also located in a just-right solar system. As discussed in this article, Planet Earth resides in such a just-right solar system.Įarth Resides in a Just-Right Solar SystemĪs discussed in An Introduction and Summary of the Evidence for the Existence of God from Design here >, Christian apologists maintain that the hundreds of finely-tuned features scientists have discovered in the universe (all of which are necessary for life to exist) are most reasonably explained by the existence of an intelligent, transcendent Designer (like the God described in the Bible) rather than mere chance as proposed by Naturalists. To support life, a planet must not only be located in a just-right location within a just-right galaxy in a just-right universe, it must also be located in a just-right solar system that has all the finely-tuned features necessary to permit a planet to support life.
