For the first time, an object in our solar system has been found more than 100 times farther than Earth is from the sun.The International Astronomical Union's Minor Planet Center announced the discovery Monday, calling the object 2018 VG18. But the researchers who found it are calling it "Farout."They believe the spherical object is a dwarf planet more than 310 miles in diameter, with a pinkish hue. That color has been associated with objects that are rich in ice, and given its distance from the sun, that isn't hard to believe. Its slow orbit probably takes more than 1,000 years to make one trip around the sun, the researchers said.The distance between the Earth and the sun is an AU, or astronomical unit -- the equivalent of about 93 million miles. Farout is 120 AU from the sun. Eris, the next most distant object known, is 96 AU from the sun. For reference, Pluto is 34 AU away.The object was found by the Carnegie Institution for Science's Scott S. Sheppard, the University of Hawaii's David Tholen and Northern Arizona University's Chad Trujillo -- and it's not their first discovery.The team has been searching for a super-Earth-size planet on the edge of our solar system, known as Planet Nine or Planet X, since 2014. They first suggested the existence of this possible planet in 2014 after finding "Biden" at 84 AU. Along the way, they have discovered more distant solar system objects suggesting that the gravity of something massive is influencing their orbit.Farout was found using the Japanese Subaru 8-meter telescope on Hawaii's Mauna Kea in November. Follow-up observations with Carnegie's Las Campanas Observatory's Magellan telescope in Chile determined its path, brightness and color."This discovery is truly an international achievement in research using telescopes located in Hawaii and Chile, operated by Japan, as well as by a consortium of research institutions and universities in the United States," Trujillo said in a statement. "With new wide-field digital cameras on some of the world's largest telescopes, we are finally exploring our Solar System's fringes, far beyond Pluto."In October, the team announced the discovery of "the Goblin" at 80 AU; it's so named because the distant solar system object was first spotted near Halloween.It's unlikely that these objects are influenced by the gravity of gas giants Neptune and Uranus because they never get close enough to them -- which indicates that something else is determining their orbits.Farout's orbit is yet to be determined."2018 VG18 is much more distant and slower moving than any other observed Solar System object, so it will take a few years to fully determine its orbit," Sheppard said in a statement. "But it was found in a similar location on the sky to the other known extreme Solar System objects, suggesting it might have the same type of orbit that most of them do. The orbital similarities shown by many of the known small, distant Solar System bodies was the catalyst for our original assertion that there is a distant, massive planet at several hundred AU shepherding these smaller objects." 3114

Harley-Davidson is trying to attract a new generation of riders at a very young age. The iconic motorcycle company announced Tuesday that it was buying StaCyc, which makes two-wheel electric bikes for kids.StaCyc has two models -- the 12eDrive and 16eDrive -- that the company describes as "the perfect choice for little rippers" between the ages of 3 and 7.The bikes have a top speed of about 10 miles per hour and sell for a range of 9 to 9.Harley-Davidson said in a statement that Harley-Davidson branded versions of StaCyc's two models will be available at select Harley-Davidson dealers in the United States in the third quarter of 2019."The StaCyc team shares the same vision we have for building the next generation of riders globally and we believe that together, we will have a significant impact in bringing the fun and enjoyment of riding to kids everywhere," said Heather Malenshek, Harley-Davidson senior vice president of marketing and brand, in the statement. Harley-Davidson is increasing its bets on electric vehicles as sales of traditional bikes slow.The company has already announced plans to launch the LiveWire premium electric motorcycle this fall. It is also developing other electric bikes that it plans to start selling in 2021.Harley-Davidson needs new growth opportunities as the company struggles to deal with tariffs from the Trump administration that have hurt earnings.Sales and profits are expected to fall this year and revenue is only expected to rebound slightly in 2020.Shares of Harley-Davidson have rallied this year with the rest of the market, rising 10% so far in 2019. But the stock is trading nearly 20% below its 52-week high. 1720

Family Dollar will close 390 stores this year and make big changes to the stores it is keeping open as the discount chain seeks a turnaround.Family Dollar sells a variety of items for under at rural and urban locations. Dollar Tree bought the company in 2015. But Family Dollar has struggled, and Dollar Tree is under heavy pressure from an activist investor to sell or revitalize the ailing line.Dollar Tree, which sells everything for and caters more to mid-income customers with suburban stores, has a plan for Family Dollar: Close stores, re-brand some locations as Dollar Tree, and renovate others with Dollar Tree merchandise sections."We are confident we are taking the appropriate steps to reposition our Family Dollar brand," Dollar Tree CEO Gary Philbin said in a news release Wednesday.This is a developing story. 846

Holiday parties are steadily making a comeback.During the last recession when people were getting laid off, businesses cut back. About 76% of human resources representatives polled said their company was having a holiday party this year. That's up about 7% from last year.A new survey form career website Monster found 60% of employees look forward to holiday parties. “It’s not a jail sentence,” said Monster career expert Vick Salemi. “It should be a fun party that you keep the professional scope top of mind.”Salemi says if you're considering skipping, instead treat it like a meeting. Go early and take advantage of face time with colleagues or bosses you don't normally get to interact with.“Think of it like I’m going to come prepared with two or three of my top wins and accomplishments this past year and I’m going to humble brag my way when I talk to my boss and my boss’ boss,” said Salemi.One thing you don't want to do is overindulge on alcohol if it's being served.About 14% of employees said they had regrets about drinking too much at a holiday party.Salemi says here's how you can recover:“You can just say I apologize if I offended anyone or I drank way too much I don’t remember much of the night. It was not my typically behavior and really just get in front of it and own it.”Keep in mind with any holiday parties with alcohol, make sure you don't wind up in any images doing questionable behavior.Click here for more 1451
