How Big Is the Solar System? – NASA Solar System Exploration

Our solar system is huge. There is a lot of empty space out there between the planets. Voyager 1 , the most distant human-made object, has been in space for more than 40 years and it still has not escaped the influence of our Sun. As of Feb. 1, 2020, Voyager 1 is about 13.8 billion miles (22.2 billion kilometers) from the Sun — nearly four times the average distance from the Sun to icy Pluto.


In an effort to bring these vast distances down to Earth, we've shrunk the solar system to the size of an American football field. If the Sun were the size of a dime on the goal line, Neptune would be 60 yards away.

StarChild: Exploring the Solar System | The Star Online

If I had a chance to explore the solar system, I'd like to to visit Venus. It is the second brightest object in the night sky after the Moon.

I would also like to land on Saturn, so I could take a closer look at the rings around it. Not only is space a fascinating place, it is also mysterious and unpredictable.

Did you know the Sun is the solar system's star? It accounts for about 99.86% of the total mass of the solar system.

Sunnova bundles roofing replacement and solar system installation

"As we continue to see rising demand for residential solar, we often find potential customers who want to go solar, but the age or condition of their roof prohibits us from being able to install solar without the replacement of their roof. This unique offering is focused squarely on addressing this issue, enabling more homeowners to choose a clean and affordable energy system with the convenience of a bundled roof and solar service from a trusted provider," said William J.

This product offering will enable homeowners to install a new, durable roof together with a state-of-the-art home solar system, helping to defer future roofing and solar removal/reinstallation expenses. In addition, the finance agreement includes a 25-year manufacturer and a 10-year workmanship warranty. In addition, Sunnova solar systems are covered by the Sunnova Protect 25-year service guarantee.

Materials Older Than the Solar System Found in Two Meteorites

Earlier in January, an international team of researchers announced the discovery of dust grains five to seven billion years old in a meteorite that landed in Australia in 1969. That makes the grains the oldest solid materials ever found on Earth — with an age that predates even our solar system itself by around two billion years.

Now, just weeks later, a different team of researchers has announced the discovery of presolar materials in a separate meteorite — and this one also landed on Earth in 1969, but on the opposite side of the planet.

WoodMac: Lifting US Import Tariffs Would Knock 30 Percent Off Solar System Prices | Greentech

Solar system prices dropped 90 percent over the last nine years, but the decline was tempered by American trade tariffs, leaving U.S. prices 45 percent above those in Europe and Australia, according to new research from Wood Mackenzie Power & Renewables. Solar products shipped from China to the U.S. face Section 201 and 301 tariffs, plus anti-dumping and countervailing duties.

The Trump administration is currently undertaking a midterm review of the Section 201 tariffs and has wide latitude to determine whether and how tariffs will continue. The U.S. Trade Representative is also soliciting comments on the tariff exclusion for bifacial solar panels, with the potential for that exclusion to be removed — again .

Scientists Are Rapidly Finding Weird Materials Older Than the Solar System on Earth - VICE

Scientists have detected grains of stardust that are older than the Sun inside a gigantic meteorite that fell in Chihuahua, Mexico, in 1969, according to a study published on Monday in Nature Astronomy . The discovery comes within weeks of another study that identified the oldest material on Earth inside a separate meteorite that also landed on our planet in 1969, this time in Australia.

In addition to raising the question of why the universe was so generous with space rocks in 1969—the same year that humanity stepped foot on the Moon for the first time—the two studies show that scientists are rapidly finding new ways to identify and study these "presolar" materials.

RIP Spitzer, the Coolest Heat Telescope in the Solar System | WIRED

On Thursday afternoon, NASA operators will send a farewell missive to the Spitzer Space Telescope from the big antenna at the Goldstone Deep Space Communication Complex in Southern California. It will take the radio signal about 10 minutes to make the 165-million-mile journey across interplanetary space. When Spitzer receives the radio command, it will boot into safe mode and relay the command back to Goldstone.

"It's going to be a bittersweet moment," says Michael Werner, a NASA astronomer who has worked as Spitzer's project scientist since 1983, when the telescope was little more than an idea. "I'm sure it's going to be somewhat painful, but I take great pride in my role in making it happen."
