That means it would take 1,351,351.35 years, using data from the (thus far) fastest manned spacecraft. As others have touched on, proposed spacecraft can travel faster. exobio says. I think Project Orion (nuclear powered spaceships) can hit up to 10% of the speed of light so that means 500 years, I think.
Medicine and Healthcare. Adults should be vaccinated with the TDaP vaccine (for tetanus, pertussis and diphtheria) every 10 years, maybe less (it is not going to be harmful to vaccinate more frequently). For diseases like whooping cough (also called pertussis), the danger to adults may be as serious as it is to children.
A DTaP booster is recommended for children ages 4 through 6 years old. Because our protection from tetanus decreases over time, older children need to get the Tdap vaccine. This booster shot contains a full dose of tetanus and lower doses of diphtheria and pertussis (whooping cough) vaccine.The Tdap vaccine is recommended for all 11 through 18 year olds, preferably at age 11 or 12 years.After getting the Tdap vaccine as a preteen or teen, adults need to get a Td (tetanus and diphtheria) booster shot every 10 years to stay protected.his booster shot contains a full dose of tetanus and lower doses of diphtheria and pertussis (whooping cough) vaccine. The Tdap vaccine is recommended for all 11 through 18 year olds, preferably at age 11 or 12 years.
