Number of Supreme Court Justices: 9.
Hours of oral arguments planned: 6.
Full impact the court's ruling could have on the country: impossible to predict.
For three days, starting Monday, the Supreme Court will hear one of the most-watched cases in a generation. It is expected to rule this summer on whether President Obama's health care law will stand as is, be partially struck down, or be thrown out altogether.
At stake is a thousand-page law that overhauls one-sixth of America's economy: the health care system.
Here's a look at the case and the law, by the numbers:
It will be almost exactly two years from the time Obama signed the health care law until the Supreme Court hears the first oral arguments on it.
Seven lawyers will appear before the court to argue all sides of the complex case.
The court has allotted six hours for oral arguments, the longest time given to one case in the past 45 years. The last time the court heard this many hours of oral arguments in one case was in 1967 when lawyers argued for eight hours.
More than half the states have joined a lawsuit led by Florida's attorney general against the Obama administration.
The challenge to the Affordable Care Act is broken into three separate cases: Department of Health and Human Services v. Florida, National Federation of Independent Business v. Secretary of Health and Human Services Kathleen Sebelius, and Florida v. Department of Health and Human Services.
Two appellate courts have ruled that the individual mandate, which requires people to have health insurance by 2014 or face a penalty, is constitutional. One court struck down the mandate and another dismissed the case against it.
Two-thirds of Americans said the Supreme Court should strike down either the individual mandate or the entire health care law, according to an ABC News/Washington Post poll released last week.
The Congressional Budget Office estimated that the Affordable Care Act would cost more than $1 trillion over 10 years.
The price tag for caring for uninsured patients was $48 billion in 2008, a cost that was passed on to doctors, insurance companies and people who did have insurance.
More than 50 million Americans did not have health insurance in 2011.
