Quantum Analysis of Ancient Space Dust Reveals Why the Inner and Outer Planets Differ. New analysis of ancient meteorite dust has provided evidence for a physical gap in the sun's protoplanetary disk.

The planets, for instance, revolve in the same direction and in almost the same plane. The four inner ones (Mercury, Venus, Earth, Mars) are smaller and denser than the outer ones (Jupiter, Saturn ...

Planets define characteristics of astrological signs. Inner planets, like Sun and Mars, have frequent influence, while outer planets like Jupiter and Saturn sway generational trends over decades.

It was much colder in the outer solar system, so water was ice, but in the region near where Earth formed, water turned to steam. Water is one of the most common chemical compounds, and its ice ...

The end result was a neat arrangement of four inner planets—Mercury, Venus, Earth and Mars—and four outer ones—Jupiter, Saturn, Uranus and Neptune—all in nearly circular but in fact ...

Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit.

The gravitational games of the outer planets removed many of those protoplanets from the inner solar system, but plenty were left behind. And then came the collisions.

A Sun-like star in our galaxy has likely eaten over a dozen of its rocky inner planets, earning it the nickname Kronos. By Jake Parks | Published: October 20, 2017 | Last updated on May 18, 2023 ...
