　　On the morning of July 25th, when many Chinese arrived at the company in the morning and were ready to start a day’s work, an asteroid that could destroy a city just passed the earth, and its name was also called "2019 OK".

　　According to the authoritative American astronomical magazine "Astronomy" reported on July 25th, an asteroid with a diameter of 57-130 meters passed the Earth at a close distance at 1: 22 am GMT)7 on July 25th (9: 22 Beijing time), with a speed of 88,500 kilometers per hour.

　　Because the asteroid’s orbit to the earth is close to the sun, which affects the observation of astronomical telescopes, scientists only discovered it one day before it came to the earth.

　　"Astronomy" magazine said that this asteroid called "2019 OK" is only 72,500 kilometers away from the Earth, which can almost be regarded as "passing by". In contrast, the average distance from the earth to the moon is about 384,403 kilometers. Therefore, the distance from the asteroid to the earth this time is only about one-fifth of the average distance between the earth and the moon.

　　In terms of size, New York Post reported on July 29th that this asteroid with a diameter of 57-130 meters may be the largest asteroid that has passed through the Earth in the past 10 years.

　　Australia’s "Sydney Morning Herald" quoted Alan Duffy, an astronomy professor, as saying on July 26 that if this asteroid accidentally falls to the earth, the energy generated by its explosion is 30 times the power of Hiroshima atomic bomb, which can "destroy a city".

　　Astronomy magazine reported that in 2013, a meteorite with a diameter of 20 meters landed in Chelyabinsk, Russia. When it passed through the atmosphere, it rubbed and burned, exploded and produced a lot of debris, forming the so-called "meteorite shower". In the falling area, the windows of many buildings were broken. The Russian side said that the incident caused more than 1,600 injuries and economic losses of about 1 billion rubles (about 108 million yuan).

　　Michael brown, an astronomy professor at Monash University in Australia, said: "It (an asteroid) is surprisingly close to the earth, which is a big thing." However, Astronomy magazine reported that an observatory in Brazil only observed the asteroid the day before it came to Earth. Astronomy pointed out that, generally speaking, observation platforms around the world will issue trajectory predictions when asteroids are far away from the Earth. If this asteroid is likely to hit the earth, these observation platforms will also give early warning to help avoid the possible disaster caused by asteroid impact.

　　But this time, the asteroid came to the line near the earth, and it had to pass through the sun, which affected the observation. "Astronomy" magazine analogy said that this is just like a baseball player can’t see the ball from the sun, and the telescope will also be affected when observing celestial bodies near the sun.

　　For asteroids that may hit the earth in the future, scientists say they have found a way. According to a report by CBS)7 on July 29th, at a news conference held by NASA in April this year, Lori Glazer, a planetary science expert of NASA, said: "If an asteroid is going to pass through the earth’s orbit, we only need to change its speed slightly to make it faster or slower, so as to avoid collision."

　　Comprehensive observer People’s Daily client

Topic: "Perception of China" in Israel.

　　Israeli society is deeply influenced by Judaism, and there are deep religious traces in many aspects of daily life. At the same time, Israel is also an immigrant country, and immigrants from all over the world have brought diverse cultures and customs to Israel.

　　dress

　　Israel wears casual clothes, basically does not wear a suit, rarely wears a tie, and even on formal occasions, few people wear a suit and tie. This is not only due to the hot climate in Israel most of the time, but also influenced by the habits since the founding of the People’s Republic of China for decades. Women are similar to modern women all over the world, but their clothes are more casual in comparison. According to Jewish regulations, men should wear a small round hat (Kippa). A rabbi in Judaism (equivalent to a priest) should wear black clothes, a black felt hat and long curly sideburns on his ears.

　　diet

　　The staple food of Jews is cakes, which are made of wheat or barley flour. Cake is regarded as the lifeline by Jews, so people usually eat cake without cutting it with a knife, but only break it with their hands, for fear of cutting the lifeline with a knife.

　　Jews in Israel have strict regulations on diet, which is called "Kosher" locally. They forbade pork and some other meats, shellfish, scaleless fish and any kind of scavengers, and meat products and dairy products could not be eaten at the same time. These people can only go to restaurants that meet the requirements of "Kosher" when eating out, and restaurants need to apply for certificates from specialized institutions composed of Jewish rabbis every year.

　　Sabbath

　　Sabbath is a weekly rest day in Judaism, which comes from Genesis (God created the world in six days and rested on the seventh day). The Sabbath begins at sunset every Friday and ends at dusk on Saturday. People eat three meals on the Sabbath, namely, Friday dinner, Saturday lunch (breakfast and lunch are combined into one) and Sabbath end meal, and Friday dinner should be the most abundant in a week. On the Sabbath, all shops are closed and buses stop running. Strictly speaking, electrical appliances are not allowed to be turned on or off on the Sabbath. If you want to use electric lights and televisions, you must turn them on before the Sabbath and keep them open until the end of the Sabbath.

　　Kibbutz (Kibbutz)

　　Kibbutz is a unique form of collective agricultural production organization in Israel, which implements the distribution principle of "from each according to his ability and equal distribution". All property belongs to the collective, and all members are completely equal. Everyone works together and lives collectively. The first kibbutz in Israel was built in 1910. At present, there are 275 kibbutz of different sizes in the country, and each kibbutz has a population of 200-3000. At present, the population living in Kibbutz is about 120,000, accounting for only about 2% of the national population, but the agricultural output value accounts for about 42% of the national total, and the agricultural products export accounts for 43% of the national total. It is the main agricultural production base in Israel. In the early days of Israel’s founding and the war years, Kibbutz made important contributions to defending the country’s survival and developing production. However, with the rapid transition of Israeli society to economic privatization and liberalization, the original collective production mode is difficult to adapt to the free competition of capitalist privatization and a series of changes brought about by it, and the call for internal reform in Kibbutz is increasing.
