When solar systems like ours first start forming, they compress from a loose-and-irregular cloud of gas and dust into a rapidly spinning, thin, flat disk. All the planets, the asteroids, and the comets form in this disk . Once that disk disappears (either through its material accreting onto planets or it getting blasted by outbursts from the young sun), all the objects still maintain that original orbital preference, something called the ecliptic plane.
You can see this effect today, as you watch the sun, the moon, and all the planets travel along roughly the same track on the sky.

Largest Rooftop Solar System in Europe Goes Online ... on Audi Factory
Audi Hungaria has just turned on the largest solar roof in Europe. The solar PV roof is the size of 22.4 football fields (soccer fields), includes 36,400 solar cells, and has a power capacity of 12 megawatts (MW).

Alfons Dintner, CEO of Audi Hungaria, called it "a symbol of our commitment to sustainability." But it’s far more than a symbol. It’s expected to generate 9.5 gigawatt-hours (GWh) of electricity a year, enough energy for approximately 9,800 average homes.

It was once thought that this period had a relatively sudden onset, but a research team at Hiroshima University and The University of Tokyo in Japan have found evidence that this bombardment period may have started much earlier, and decreased in intensity over time.

Spitzer space telescope legacy -- ScienceDaily
To understand the significance of the Spitzer Space Telescope on the understanding of our solar system, think of what the steam engine meant for the industrial revolution.
A national team of scientists today published in the journal Nature Astronomy two papers that provide an inventory of the major discoveries made possible thanks to Spitzer and offer guidance on where the next generation of explorers should point the James Webb Space Telescope (JWST) when it launches in October 2021.
The Fastest Car In Our Solar System, Tesla's Starman Has Its Closest Approach To Mars | Torque
According to Elon Musk, after more than two years in space, Tesla's Starman has its closest approach to Mars. Getting within 0.05 astronomical units or 4.6 million miles of the red planet, this will be the closest Tesla's first-generation Roadster will be to Mars, till August 22, 2035.
After being launched on SpaceX's Falcon Heavy rocket's test flight, Elon Musk's personal midnight cherry red Roadster has spent the last two and a half years orbiting the sun.
What is interstellar space? | Astronomy Essentials | EarthSky
You might be surprised to learn that interstellar space isn’t just vacuum. It’s full of gases, elements, and dust – very thinly spread, to be sure – but the building blocks of stars and planets.
In this infrared image from NASA's Spitzer Space Telescope, winds flowing out from a fast-moving star (Zeta Ophiuchi) are making ripples in the dust in interstellar space. Image via NASA .
Interstellar space – the space between the stars – isn’t just empty space . There’s a lot of “stuff” out there, including hydrogen (70%) and helium (28%), formed in the Big Bang that set our universe into motion. The other 2% of “stuff” in interstellar space is heavier gases and dust , consisting of the other elements made inside stars and spewed into space by supernovae. The material in interstellar space is very spread out.
