Upside Down Orbits Of Planets In Far Away Solar System Confusing Scientists
The defining characteristic of a far-off solar system is startling scientists . In our solar system, planets complete their orbits around the Sun's equator - horizontally aligning with the Sun during the orbit.
In this strange solar system situated 150 light-years away, scientists found that two planets are in polar orbits . This means that they rise above and dip below the poles of their Sun instead of circling it in a flat line like planets in our solar system .
EarthSky | Weird rocky exoplanets unlike any seen before
Exoplanets – worlds orbiting other stars – appear to be scattered throughout our Milky Way galaxy. Astronomers estimate they number in the billions. A good percentage of those worlds are rocky, like Earth or Mars in our solar system, for example. But are they similar?
The researchers analyzed the elemental remains of such worlds that “polluted” the atmospheres of their host stars – evolved stars known as white dwarfs – after the planets disintegrated.

Jupiter is well-known for being the biggest planet in our solar system, and it's also home to the biggest storm. It's called the Great Red Spot, an enormous vortex that has been swirling for centuries. It's bigger than our own planet, and yet we don't know much about it.
Professor finds possible ninth planet in our Solar System
A leading British astronomer believes he has found possible evidence of a ninth planet in the Solar System.
His data suggest the new world would be three to five times more massive than the Earth, and orbiting the Sun at about 225 times the distance of our own planet.
MSU releases solar system planning and zoning guide
Michigan State University (MSU) Extension has released a resource guide, "Planning & Zoning for Solar Energy Systems: A Guide for Michigan Local Governments."
The new online guide will help Michigan communities become solar-ready by offering best-practice guidance for addressing solar energy systems (SES) within their planning policies and zoning regulations.
Spacecraft to study Trojan asteroids - Delaware Gazette
The spacecraft Lucy is on its way. On Oct. 16, 2021, an Atlas V launch vehicle lifted Lucy into its 12-year, 4-billion-mile journey to explore the Jupiter trojan asteroids.
Like the henna-haired Lucy of old, Lucy “has some ‘splaining to do,’” this time about our solar system’s early days. (Those younger folks who do not understand the Lucy allusion above should ask their grandparents.)
NASA solar probe that 'touched the sun' is being bombarded by plasma explosions - CNET
But Parker is learning a lesson about the consequences of its great speed: constant bombardment by space dust.
Space dust is a pervasive element of our solar system and likely many other planetary systems in the universe. Tiny particles of dust, a quarter the width of a human hair and generated by asteroids and comets, are locked in a forever dance around the sun.
Planetologists investigate origin of heavy bombardment of the moon 3.9 billion years ago
But what was the origin of this late bombardment and where did the asteroids that hit the moon come from? Scientists discuss two possibilities.
The scientists from Münster examined lunar rocks that were formed during the bombardment 3.9 billion years ago. These rocks contain tiny metal globules consisting of material from the impactor asteroids.
