Scientists working for a NASA-funded project at the University of Arizona said that a possible "mini moon" is currently orbiting the Earth. Kacper Wierzchos of the Catalina Sky Survey tweeted this week that an object, 2020 CD3, has been captured by Earth's gravitational pull, and is temporarily in orbit around the Earth. The object is not very large, only 6 to 11 feet, Wierzchos said, but he added it is still an extraordinary discovery. "it's a big deal as out of ~ 1 million known asteroids, this is just the second asteroid known to orbit Earth (after 2006 RH120, which was also discovered by the Catalina Sky Survey)," he tweeted. 2020 CD3 began orbiting the Earth three years ago. Elon Musk, the head of Tesla, jokingly tweeted, "It’s not mine." Tesla sent a Roadster into space in 2018. BIG NEWS (thread 1/3). Earth has a new temporarily captured object/Possible mini-moon called 2020 CD3. On the night of Feb. 15, my Catalina Sky Survey teammate Teddy Pruyne and I found a 20th magnitude object. Here are the discovery images. 1049

Severe weather plagued several states throughout the Midwest over the weekend, killing one person and damaging at least one building.Vickie Darnel, 64, died from drowning Sunday after she drove into a flooded creek crossing in Le Flore County, Oklahoma, according to Lt. Kera Philippi, spokeswoman for the Oklahoma Highway Patrol.Philippi says that Darnel's vehicle was swept off the roadway around 4:30 a.m. Sunday near the border of Arkansas.The area saw a number of flash flood and severe thunderstorm warnings from the National Weather Service over the weekend.The National Weather Service is sending an assessment team to South Bend, Indiana, after a tornado touched down in the area and destroyed at least one building.The building was the site of Growing Kids daycare facility, according to Aaron Miller, dispatch supervisor for St. Joseph County Public Safety Communication Center.Miller told CNN that the building suffered extensive damage and there were several reports of trees down throughout St. Joseph County.Missouri State Highway Patrol along with the Missouri Department of Conservation and several local agencies performed multiple water rescues Sunday for people whose vehicles were in the water.They also rescued people who were stranded by high water due to heavy rainfall, according to the Missouri Department of Public Safety.A subdivision in Neosho, Missouri, and parts of Roaring River State Park had to be evacuated, although it was unclear how many people had to leave, the Missouri Department of Public Safety said.The band of weather that caused all of this chaos is called a frontal boundary and it acts as a cold front but doesn't actually have any cold air behind it.The mixture of the boundary layer is slightly cooler dry air and hot humid air which can cause intense storms. 1821

Saturday marks the "First in the West" nomination race with Democrats in Nevada caucusing at a critical time in the campaign for the remaining Democratic field. While New Hampshire and Iowa gave Sen. Bernie Sanders and Mayor Pete Buttigieg some early momentum, Nevada is the first state that will include a diverse voting base. The Nevada Democratic Party says the Nevada Caucuses is a good litmus test on who could best represent the party and be the Democrats' standard-bearer in 2020. After Iowa, all eyes on the tabulationUnlike most primaries, which are run by state boards of election, caucuses are run by the party. Two weeks ago, the Iowa Democratic Party came under fire for a failed vote tabulation as results took several days to be compiled. The fiasco in Iowa was caused by a glitch in an app, and forced the state party chair to step down. Democrats are hopeful that technology does not fail them again. Nevada Democrats too are going to rely on technology. Precincts will each use an iPad with a Google Drive document used to report real-time numbers back to the party. Precinct chairs will also be asked to call the Democratic Party, and send a picture via text message of the paper tabulation that is signed off by representatives of the viable campaigns. How a caucus worksCaucuses are more akin to community events rather than a typical election. Rather than using a secret ballot, caucus goers will first hear from supporters of the candidates, representatives of the campaigns, or perhaps even from the candidate themselves.Then, those on hand will literally "take sides," and join with other supporters of that campaign. At the precinct, a determination is made of viable and non-viable candidates (generally 15% is the threshold).The supporters of non-viable candidates will then be given 15 minutes to join a viable campaign, or abstain. Once the 15 minutes are up, a tally is taken, and the Nevada Democratic Party releases the number of delegates won by each candidate, which is the most important figure of the day. The party will also release popular vote totals.How are ties brokenIf there is a tie at a caucus site that would affect the number of delegates, the precinct chair will use a deck of cards to break the tie. This is Nevada after all. What is at stake on SaturdayFor Saturday's Nevada Caucuses, a total of 36 national delegates will be up for grabs. The Democrats divvy delegates in a proportional basis, meaning with a wide-open field, it is likely that a candidate will not receive a majority of the delegates on Monday.But with Nevada representing some of the first votes cast in the nomination process, it is important to do well for fundraising and momentum purposes.Where the race standsButtigieg holds a slight lead in delegates over Sanders (23-21). Other candidates with delegates are Sen. Elizabeth Warren (8), Sen. Amy Klobuchar (7) and VP Joe Biden (6). Mayor Michael Bloomberg did not enter the first two nominating contests, and will sit out Saturday’s Nevada Caucuses and the South Carolina Primary on Feb. 29.Although Buttigieg holds the lead in delegates, it is hard to describe him as the frontrunner. Sanders has a plurality of votes, and leads national polling.Polls in recent weeks have consistently shown Sanders in the lead in Nevada. He also has been leading nationally.Real Clear Politics tracks major opinion polls, and an aggregate of polls show that Sanders has seen his share of the vote go from 19% to 27% in the last three weeks. During that time, Bloomberg has seen his numbers more than double, as he has gone from the back of the pack to nearly even with one-time frontrunner Biden for second.But on March 3, the biggest night of the nominating race awaits as more than a dozen states, including Texas and California, hold primaries. These states are already conducting early voting, meaning Wednesday’s debate could be the final opportunity for candidates to make an impression before a crucial Super Tuesday race. 4002
