Would a blind astronaut be able to sense the gravity of an object? Would an astronaut lost inside the Sun be able to sense which way is the core?

Would a blind astronaut be able to sense the gravity of a nearby star/planet/moon?

Would an astronaut lost somewhere inside the Sun be able to sense which way is the core and which way is the surface?

Notes:

• For question 1, the astronaut is in the vacuum of space, the pressure outside of his spacesuit is in the order of $10^{-10}$ Pa.
• For question 2, the futuristic spacesuit of the astronaut can resist the high temperatures inside the Sun.
• For both questions, the astronaut does not have any object at his disposal, he cannot communicate with anyone else and his spacesuit does not have any integrated devices.
