Size comparison: The M87 Black Hole and Our Solar System [Caption at top left of the panel:] EHT Black Hole Image Source: NSF [An image of the M87 black hole captured by the event horizon telescope on the day that this comic was published is shown, in the shape of a thick red-and-yellow ring on a black … It's 24 billion miles across and contains the same mass as 6 1/2 billion suns. Take this black hole, for example. 2020-07-08T14:30:00Z Anyone else find it ironic for an IP editor to refer to logged-in editors as IP editors? CHECK OUT OUR MERCHANDISE HERE FOLLOW US! It's nearly twice the size of Jupiter, spanning a region about 172,000 miles wide, but inside is as much mass as 47,000 suns.But these black holes are nothing compared to supermassive black holes, like Sagittarius A*, which lives at the center of our Milky Way galaxy. I am trying to spread truth and good critical thinking, but IP editors keep reverting My well-intention edits! To make Earth into a black hole, for instance, you'd have to shrink it to less than an inch across.But real black holes are much larger than that and pack way more mass than Earth.
It all depends on how much mass is inside. Take this black hole, for example. The location Randall notes would correspond closer to Voyager II than I(9.3 billion miles away from earth vs 11 billion miles). This is the only black hole whose mass has been measured directly by observing the full orbit of a circling star. However, the radius of a black hole’s event horizon is directly dependent on its mass, so in this case we can answer the question, "How big is a black hole?" The magnitude is incomprehensible. You see, the more mass you can shrink into a small space, the stronger your gravitational force will become. At 1,460 miles across, it's nearly large enough to stretch from Florida to Maine and, according to some calculations, contains the mass of 400 suns.At this point, black holes start to get pretty big compared to Earth, but it's still nothing when you consider the sheer mass they carry. The smallest are stellar black holes, which form after a giant star explodes and collapses in on itself, like this one, which measures about 40 miles across, roughly three times the length of Manhattan. Turns out, when it comes to the cosmos, size isn't the only thing that matters. But in that small space is enough mass to equal 11 of our suns.In another galaxy, called M33, there's a black hole that is 58 miles across and packs as much mass as 15.7 suns inside.Up next are the intermediate-mass black holes, like this one. It's 24 billion miles across and contains the same mass as 6 1/2 billion suns. Is anyone agreeing with the source ? The smallest are stellar black holes, which form after a giant star explodes and collapses in on itself, like this one, which measures about 40 miles across, roughly three times the length of Manhattan. Such incredibly compact objects cause infinite curvature in the fabric of spacetime. You see, the more mass you can shrink into a small space, the stronger your gravitational force will become. But this supermassive black hole, as large as it is, could still fit within our solar system with plenty of room to spare.So we have to look at one of the most massive of all supermassive black holes. Now that may sound big, but Sagittarius A* is small compared to other supermassive black holes.Take the one at the center of our neighbor the Andromeda galaxy, which has a diameter of 516 million miles, larger than Jupiter's orbit, and contains enough mass to equal that of 140 million suns. --I Googled to get a sense of scale. Going to edit this but wanted to add discussion here as well. It's nearly twice the size of Jupiter, spanning a region about 172,000 miles wide, but inside is as much mass as 47,000 suns.
