Within the United States, a Senior Senator is the longer continuously serving senator from any state's delegation to the Senate of the United States. Every State sends two Senators to the US Senate, with a "Senior" Senator and a "Junior" Senator Colleague. If Senators are sworn in on the same day, other factors, such as being a former US Representative and the length of time served as a US Representative, or being a former Governor also factor into seniority.
Seniority plays an important role within the Senate in allowing Senior Senators preference in choosing which committees they serve on. It also determines where in the Senate senators sit, and factors into the allotment of office space. Seniority also determines the ceremonial order of officials at diplomatic and social events (known as the United States order of precedence). The President pro tempore of the Senate, who presides over the Senate, is usually the most senior Senator from the current Majority Party.
The difference is that the senior Senator has been in office longer than the junior Senator.
