Scientists know that when the universe came into being, not everything in it spontaneously appeared. How long has our solar system been around?
Astronomers estimate the age of our Solar System is 4.57 billion years, but how have they arrived at this number? ; We can tell how old the Solar System is by looking at other planets around other stars. ; From looking at infant planets in other systems, we know that worlds form at the same time as their stars.
How old is each planet? Do we know the order in which the planets in our solar system formed? · Robert Hawk Canal Winchester, Ohio · Estimating ages of specific events is one of the most difficult problems in astrophysics. While we have a precise (and probably accurate) age for the solar system, we do not have precise ages for each planet. The solar system’s age comes from radiometric dating of rock samples from Earth, the Moon, and meteorites. If an isotope of one element decays into an i...
What is our Solar System and how many stars does it have? How did the Sun and Solar System form, and what are other planetary systems like?
How old is the Solar System? That is a question that cuts to the heart of it all. By studying several things, mostly meteorites, and using radioactive dating techniques, specifically looking at dau...
The Good ; Ghost craters appear as faint circular outlines in the otherwise smooth-looking lunar maria, almost like a road pothole that has been tarred over, but the outline of the “crater” remains barely visible. Since the ghost craters were modified by the volcanic overflow that formed the maria, those craters predated the volcanic overflow. But the ghost craters had to have formed after the impacts which caused the lava flows. This cause-and-effect suggests a very short time between the c...

The way we dreamed our solar system before space probes woke us to the facts
By measuring radioactive elements in rocks from Earth and other parts of the solar system, scientists can develop a timeline of our planet's early years.
